“M.D.” vs. “Ph.D.” vs. “Dr.”: Are They Synonyms?

Quick: when you hear the word doctor , what do you picture?

Most would probably describe someone in a white lab coat with a stethoscope hanging around their neck or someone in medical scrubs—someone you would seek out if you have a deep cut that needed stitches.

That word doctor , however, is a title assigned to many who don’t come close to that description, many of whom you wouldn’t want stitching up that cut. Take your English professor, for instance. No offense, Dr. Barrett. 

It can all be a bit confusing, which is why it’s important to know who and why someone might be called a doctor , as well as what all those initials and abbreviations after their name mean. Here we break it all down.

What does Dr. mean?

Let’s start with doctor or D r . for short. While the first definition of the word is “ a person licensed to practice medicine,” that doesn’t mean you want to take medical advice from anyone who calls themselves a doctor . There are many looser definitions of the word that follow and, frankly, make things a bit confusing.

For example, the third definition is older slang for a “cook, as at a camp or on a ship,” while the seventh entry is “an eminent scholar and teacher.” Bugs Bunny didn’t help matters either by plying anyone and everyone with his famous greeting,“What’s up, doc?” 

The term doctor can be traced back to the late 1200s, and it stems from a Latin word meaning “to teach.” It wasn’t used to describe a licensed medical practitioner until about 1400, and it wasn’t used as such with regularity until the late 1600s. It replaced the former word used for medical doctors— leech , which is now considered archaic. 

WATCH: When Did The Word "Doctor" Become Medical?

Physician vs. doctor : are these synonyms.

While the term physician is a synonym for doctor , it’s typically used to refer to those who practice general medicine rather than those who perform surgery, aka surgeons . 

A quack , on the other hand, is defined as “ a fraudulent or ignorant pretender to medical skill.”

What does M.D. mean?

Moving on to initials that carry more weight than a nod from Bugs, let’s look at M.D.s .

M.D. , which can be used with or without the periods ( M.D. or MD )  is the designation for a medical doctor. This is earned by attending medical school (typically a four-year program after completing at least one undergraduate degree, plus a residency program), and learning to diagnose patients’ symptoms and offer treatment. 

The initials M and D stem from the Latin title  Medicīnae Doctor. There are many different types of doctors, with different specialties, but if you have a physical ailment, visiting a doctor with the initials M.D. is a good place to start.

Specialty doctors may add even more initials to their title, such as DCN (doctor of clinical nutrition), DDS (doctor of dental surgery), or countless others they acquire with additional training. To make things even more confusing, some may add abbreviations from medical associations they belong to, such as FAAEM (Fellow of the American Academy of Emergency Medicine).

What does Ph.D. mean?

As for Ph.D. , this stands for “doctor of philosophy.” It stems from the Latin term Philosophiae Doctor.

You can get a Ph.D. in any number of subjects, from anthropology to mythological studies. It’s not an easy feat, however, as to earn one, you must do original research and write a dissertation . 

Ph.D. vs. M.D .: are these synonyms?

There are two big differences between Ph.D. s and M.D .s. When it comes to medicine, M.D.s can prescribe medications, and Ph.D.s can’t. And yes, it’s possible to be both an M.D. and a Ph.D. In fact, some med schools offer programs in which you can achieve both simultaneously. 

You can also get a professional doctorate degree in a number of fields. For example, you might receive a doctorate of education, an  Ed.D . 

So, in a nutshell, both M.D.s and Ph.Ds can be referred to as doctors . If you’re looking for someone to treat what ails you physically, then you want at least an M.D. following their name. If you want to dig deep into a subject and get advice from someone who has done their own research and who likely knows the latest and greatest developments in a particular area, then you’re probably looking for a Ph.D. And if someone has both, even better—depending on your needs, it may be just what the doctor ordered.

How to Correctly Use the Titles Dr. & PhD With a Name

How to Reference a Person With a PhD

How to Reference a Person With a PhD

When someone has earned a Doctor of Philosophy, or Ph.D., degree, that person is subsequently referred to as “doctor” in formal speech. The same is true of a person who is a medical doctor, psychologist, dentist or veterinarian. In formal speech, that person should be referred to as “doctor.” However, the rules are different in written form when addressing someone who is called “doctor” in formal speech. In written form, the titles “Dr.” and “Ph.D.” are not interchangeable.

Determine the Type of Doctor

First, you should identify what type of doctor you are addressing. Doctors of medicine and psychology, doctors of dentistry and doctors of veterinary medicine must be addressed differently in comparison to academic doctors who have earned a Doctor of Philosophy doctoral degree. Be advised that there are different types of doctoral degrees. A Doctor of Philosophy degree is just one kind of doctoral degree. There’s also, for example, a Doctor of Education doctoral degree and a Doctor of Psychology doctoral degree. The titles associated with the various doctoral degrees are not interchangeable. Only a person who has earned a Doctor of Philosophy degree should be addressed as Ph.D.

Addressing a Doctor in Writing

Place the title of “Dr.” before the name of a person who is a doctor of medicine or psychology, doctor of dentistry, or doctor of veterinary medicine. For example Dr. George Ross. Always write the word “doctor” in its abbreviated form when it goes before the person’s name. Never write, for example, Doctor George Ross. Do not combine the title of “Dr.” with any other title even if the person could appropriately be addressed by a different title. Never write, for example, “Dr. George Ross, Ph.D.,” even if the person is a medical doctor who has also earned a Doctor of Philosophy degree. Pick one title. Do not use the “Dr.” title when referring to someone who is solely an academic doctor.

Put a comma followed by the title “Ph.D.” after the name of a person who has earned a Doctor of Philosophy doctoral degree. For example Stacey Childs, Ph.D. Do not combine the title of “Ph.D.” with any other title even if the person could appropriately be addressed by a different title. For instance, even if the person being addressed is a doctor of medicine who has also earned a Ph.D., never write, for example, Dr. Stacey Childs, Ph.D. Pick one title. Do not use the “Ph.D.” title when referring to someone who not earned a Doctor of Philosophy doctoral degree.

What Is a Doctorate Degree?

A doctorate is usually the most advanced degree someone can get in an academic discipline, higher education experts say.

What Is a Doctorate?

It's unwise to apply to a doctoral program if you don't have a clear idea of how you might use a doctorate in your career.

In many academic disciplines, the most advanced degree one can earn is a doctorate. Doctorate degree-holders are typically regarded as authorities in their fields, and many note that a major reason for pursuing a doctorate is to increase professional credibility.

"If someone wants to be respected as an expert in their chosen field, and also wants to have a wider array of options in research, writing, publishing, teaching, administration, management, and/or private practice, a doctorate is most definitely worth considering," Don Martin, who has a Ph.D. in higher education administration , wrote in an email.

A doctoral degree is a graduate-level credential typically granted after multiple years of graduate school, with the time-to-degree varying depending on the type of doctoral program, experts say.

Earning a doctorate usually requires at least four years of effort and may entail eight years, depending on the complexity of a program's graduation requirements. It also typically requires a dissertation, a lengthy academic paper based on original research that must be vetted and approved by a panel of professors and later successfully defended before them for the doctorate to be granted.

Some jobs require a doctorate, such as certain college professor positions, says Eric Endlich, founder of Top College Consultants, an admissions consulting firm that helps neurodivergent students navigate undergraduate and graduate school admissions.

Endlich earned a Doctor of Philosophy degree, commonly known as a Ph.D., from Boston University in Massachusetts. He focused on psychology and notes that a doctoral degree is generally required to be a licensed psychologist.

"Since a Ph.D. is a research-focused degree, it can be advantageous to those seeking high-level research positions in scientific fields such as astrophysics or biotechnology," he says.

How Long it Takes to Get a Doctorate Degree

Martin, founder and CEO of Grad School Road Map, an organization that helps grad school applicants navigate the admissions process, says obtaining a doctorate is often a lengthy endeavor.

"Typically it can take between four and six years to complete any doctoral program," he says. "If comprehensive examinations and a dissertation are part of the graduation requirements, it may take a year or two longer. There is no standard amount of time – some students take seven to 10 years to finish."

Endlich says doctoral degree hopefuls should be aware that completing a dissertation may take a long time, especially if unexpected hurdles arise.

"My dissertation, for example, involved recruiting college students to complete questionnaires, and it took much longer than I anticipated to recruit enough subjects for my study," he says.

The standards for a dissertation, which include the proposal and research, are rigorous and usually involve a review and approval by a faculty committee, says Hala Madanat, vice president for research and innovation at San Diego State University in California.

"As part of dissertation requirements, some programs will require publication of the research in high-impact peer-reviewed journals," Madanat wrote in an email.

Types of Doctoral Degree Programs

According to professors and administrators of doctoral programs, there are two types of doctorates.

Doctor of Philosophy

A doctor of philosophy degree is designed to prepare people for research careers at a university or in industry, and teach students how to discover new knowledge within their academic discipline. Ph.D. degrees are offered in a wide range of academic subjects, including highly technical fields like biology , physics, math and engineering; social sciences like sociology and economics; and humanities disciplines like philosophy.

A Ph.D. is the most common degree type among tenure-track college and university faculty, who are typically expected to have a doctorate. But academia is not the only path for someone who pursues a Ph.D. It's common for individuals with biology doctorates to work as researchers in the pharmaceutical industry, and many government expert positions also require a Ph.D.

Professional or clinical doctorates

These are designed to give people the practical skills necessary to be influential leaders within a specific industry or employment setting, such as business, psychology , education or nursing . Examples of professional doctoral degrees include a Doctor of Business Administration degree, typically known as a DBA; a Doctor of Education degree, or Ed.D.; and a Doctor of Nursing Practice degree, or DNP.

A law degree, known as a juris doctor or J.D., as well as a Doctor of Medicine degree, or M.D., are also considered professional doctorates.

How to Get a Doctorate

Getting a doctorate is challenging. It ordinarily requires a series of rigorous classes in a field of study and then passage of a qualification exam in order to begin work on a dissertation, which is the final project.

Dissertations are difficult to write, says David Harpool, vice president of graduate and online programs at Newberry College in South Carolina. Some research indicates that only about half of doctoral students go on to finish their degree, and a main reason is that many never finish and successfully defend their dissertation

"Many of them are in programs that permit them to earn a master’s on the way to a doctorate," Harpool, who earned a Ph.D. from Saint Louis University in Missouri and a J.D. from the University of Missouri , wrote in an email. "The transition from mastering a discipline to creating new knowledge (or at least applying new knowledge in a different way), is difficult, even for outstanding students."

Learn about how M.D.-Ph.D. programs

There is a often a "huge shift in culture" at doctoral programs compared to undergraduate or master's level programs, says Angela Warfield, who earned a Ph.D. in English from the University of Iowa.

Doctoral professors and students have more of a collaborative relationship where they function as colleagues, she says. And there's pressure on each student to produce "significant and original research."

Many full-time doctoral students work for the school as researchers or teaching assistants throughout their program, so time management is crucial to avoid burnout. However, the dissertation "is by far the biggest battle," she says. The goal is to avoid an "ABD," she says, meaning "all but dissertation."

"In my writing group, we had two motivational slogans: 'ABD is not a degree,' and 'a good dissertation is a done dissertation,'" Warfield, now the principal consultant and founder of admissions consulting firm Compass Academics, wrote in an email.

How Are Doctorate Admissions Decisions Made?

Admissions standards for doctoral programs vary depending on the type of doctorate, experts say.

The quality of a candidate's research is a distinguishing factor in admissions decisions, Madanat says. Meanwhile, leaders of clinical and professional doctorate programs say that the quality of a prospective student's work experience matters most.

Doctoral programs typically expect students to have a strong undergraduate transcript , excellent letters of recommendation and, in some cases, high scores on the Graduate Record Examination , or GRE, Endlich says.

"The size of the programs may be relatively small, and universities need to be sure that applicants will be able to handle the demands of their programs," he says.

Because professional doctorates often require students to come up with effective solutions to systemic problems, eligibility for these doctorates is often restricted to applicants with extensive first-hand work experience with these problems, according to recipients of professional doctorates.

In contrast, it's common for Ph.D. students to begin their programs immediately after receiving an undergraduate degree. The admissions criteria at Ph.D. programs emphasize undergraduate grades, standardized test scores and research projects , and these programs don't necessarily require work experience.

Admissions decisions may also depend on available funding, says Madanat, who works with doctoral students to provide funding, workshops and faculty support to help their research.

Who Is a Good Fit for a Doctoral Program?

Doctoral degree hopefuls "should be interested in making a deep impact on their field, open-minded, eager to learn, curious, adaptable and self-motivated," Madanat says. "Doctoral programs are best suited for those whose goals are to transform and change the fields they are studying and want to make a difference in the way the world is."

Someone who loves to study a subject in great depth, can work alone or in teams, is highly motivated and wants to develop research skills may be a good candidate for a doctoral program, Endlich says.

Because of the tremendous effort and time investment involved in earning a doctorate, experts say it's foolish to apply to a doctoral program if it's unclear how you might use a doctorate in your career.

"The students are being trained with depth of knowledge in the discipline to prepare them for critical thinking beyond the current state of the field," Madanat says. "Students should consider the reasons that they are pursuing a doctoral degree and whether or not it aligns with their future professional goals, their family circumstances and finances."

Rachel D. Miller, a licensed marriage and family therapist who completed a Ph.D. degree in couples and family therapy at Adler University in Illinois in 2023, says pursuing a doctorate required her to make significant personal sacrifices because she had to take on large student loans and she needed to devote a lot of time and energy to her program. Miller says balancing work, home life and health issues with the demands of a Ph.D. program was difficult.

For some students, the financial component may be hard to overlook, Warfield notes.

"Student debt is no joke, and students pursuing graduate work are likely only compounding undergraduate debt," she says. "They need to really consider the payoff potential of the time and money sacrifice."

To offset costs, some programs are fully funded, waiving tuition and fees and providing an annual stipend. Some offer health insurance and other benefits. Students can also earn money by teaching at the university or through fellowships, but those adding more to their plate should possess strong time management skills, experts say.

"Graduate school, and higher education in general, can be brutal on your physical and mental health," Miller wrote in an email.

But Miller says the time and effort invested in her doctoral program paid off by allowing her to conduct meaningful research into the best way to provide therapy to children affected by high-conflict divorce and domestic violence. She now owns a therapy practice in Chicago.

Miller urges prospective doctoral students to reflect on whether getting a doctorate is necessary for them to achieve their dream job. "Really know yourself. Know your purpose for pursuing it, because that's what's going to help carry you through."

Is a PhD a Doctor? [The full guide]

The term “Dr” is very prestigious and projects expertise and respect in those who use it. There is a long and complicated history with the doctor title and who should (and shouldn’t) use it. Medical doctors, lecturers, and other medical professionals use it, but where did it come from and is a PhD a doctor?

Yes, a person with a PhD is a Doctor and use the “Dr” title before their name. This is not to be confused with a medical doctor. There is a complex history with this term but is currently accepted for people who hold a PhD as well as a wide range of other professions.

I have a PhD in chemistry and I call myself Doctor Stapleton in professional settings and when I want to let certain entities know that I have been awarded a PhD. In my experience, other PhD holders mainly use their titles in a similar way.

This article will cover everything you need to know about the Dr title and who can and cannot use it.

There have been people who have argued that the term doctor should be reserved for people who have studied and are practising medicine so that there is little confusion about the people suitably qualified to make health care decisions for you.

However, as you will see through this article the doctor title has a very long history that has nothing to do with the medical field at all.

Where the term Doctor comes from

For those that love a little bit of word history:

is a PhD a doctor

The word doctor comes from the Latin verb ”docere” which means to teach or is used to refer to a scholar.

In history the doctor title was invented to signify that a person was an imminent scholar. The doctorates date as far back as the 1300s and those who were able to get the doctor title in front of their name were rewarded with a lot of respect and prestige.

These people were often the lecturers of their day and would therefore teach many students in their areas of expertise.

Therefore, I think it is reasonable to conclude that the original intended use of doctor was for academics and scholars.

As time went on, the doctor title was awarded to other professions that wanted to elicit the same level of respect and prestige.

Health professionals receive an undergraduate degree in medicine and can call themselves doctor. However, these are professional degrees (undergraduate qualifications) and not really considered doctorates in the true sense of the word – it is more of an honorary title.

I don’t think that anyone with a PhD really cares about who is using it and accept that the majority of the public think that anyone with a doctor title has a medical degree.

I know that I was very excited to receive my doctor title but the excitement soon wears off when you realise that it doesn’t really matter in everyday life – but it still makes you and your parents proud.

These days, the doctor title is used by a variety of non-academic professions and it can get a little bit confusing.

So let’s have a look at who can actually use the doctor title and where it came from.

Who can use “doctor”

Even though the original use of the doctor title was for imminent scholars, nowadays there are several different professional qualifications that can use the doctor title.

It’s no surprise that more professional qualifications want to use the doctor title as it indicates many years of study, status and makes parents very proud.

A 2016 peer-reviewed publication submitted to the Canadian Medical Association Journal asks who is entitled to the title of Doctor?

Exactly who can use this term is starting to get a little bit confusing for the public.

There are many honorific doctor titles, including those found in the table below.

The use of the doctor term for many healthcare-related qualifications can cause a fair bit of confusion about what qualification the person has achieved.

That is why the title of a person is only the second most important thing to look at.

If in doubt, have a look at the letters after their name to really understand what the doctor title is referring to.

There are some interesting deviations in the doctor title and interestingly, in the UK, surgeons do not refer to themselves as doctor but rather use the term Mr/Miss/Mrs/Ms etc. I had a family friend who was a brain surgeon who was a medical doctor and, after becoming a surgeon, changed back to Mr – a prestigious indicator in the medical field.

It’s strange to me how each field has its own customs to denote prestige.

There are arguments that in a professional and medical setting that the term doctor should be reserved for those who are medical doctors.

This can be difficult as many other healthcare professionals have also received doctorates in their specialisation and would want recognition for that effort and achievement.

In a 2011 article in the New York Times , physicians said that they were worried about losing control over the title of doctor because it could lead to a loss of control over the perception of the medical profession itself.

Anything that makes it more difficult for patients to make an informed decision about their healthcare could be very dangerous.

However, the fact that they are using this doctor title at all is a deviation from its original intention. Here is why the doctor title really is only meant for holders of a Doctor of Philosophy.

PhDs – the original doctors(?)

PhD stands for Doctor of Philosophy and, arguably, accounts for the only true use of the doctor title.

Being awarded a PhD means that you have completed postgraduate original and/or applied research that adds a significant contribution to the knowledge in a particular field.

It could be a PhD gained at a university or a professional doctorate but should signify that the owner of the title has completed the highest qualification obtainable in their field.

I talk about this in my short YouTube video:

You don’t necessarily have to use your doctor title after you have your PhD.

I know that there are many people who only use their Dr title in professional settings or as a way to stand out in other settings.

I only use my PhD title when I am in a setting where it is traditionally used. For example, I use my doctor title if I am giving a talk at a university or I am applying for funding within my field of expertise.

Some PhD holders find it a little bit awkward using their Dr title in everyday life whilst others use it on everything from rental applications to restaurant bookings.

How people use their Dr title once they have one is completely up to personal and individual choice. Initially, I was very excited to use my doctor title in as many situations as possible but quickly became wary of using it when it wasn’t required.

However, one of my guilty pleasures is seeing my doctor title on a plane ticket – I’m not quite sure why that is!

What you should call a PhD holder/your lecturers

One of the most common questions that I get asked when I am lecturing at a university is what students should call their lecturers.

Students can get confused with all of the formalities – especially if they have never been in a university before.

Professors, associate professors, doctors, lecturers, researchers – what does it all mean and how should you refer to academics?

Ultimately, it depends on the person.

Some PhD holders who lecture in a university want to be called by their official title and surname during every interaction.

Other lecturers and PhD holders are happy with students calling them by their first name. I certainly didn’t mind people calling me Andy during my workshops or lectures.

Also, some cultures are much more formal than others and wish to show respect by always using the official title of an academic.

Feel free to use whichever mode of interaction you wish – but, as a general rule, always err on the side of caution and use the more formal term for safety. Quite often, I have seen academics prompt students to use their first name as they also feel a little bit awkward being called their professional titles.

Doctor vs professor

When you graduate from a PhD you are entitled to call yourself by the doctor title.

All PhD holders are called Doctor in their professional setting. This can be on business cards, newsletters, websites, and other official documentation.

Universities in some countries also have a graduated career progression title system which denotes the expertise and seniority of the academic.

For example, in Australia the academic system is graduated like this:

  • Senior lecturer
  • Associate Professor

Therefore, in Australia it is not always appropriate to call someone in a university professor. Even if they are teaching your subject.

Professor is reserved for those who have achieved demonstrated expertise and outcomes in a variety of academic areas such as administration, teaching, research, and community outreach.

In other countries, however, you are automatically deemed a professor if you are teaching at a university. For example, in America your students will refer to you as a professor no matter your seniority in your university.

One of the first things you should do if you want to talk to your lecturer in a university setting is ask what their preference would be to be called.

Ask your lecturer about their preference

Whenever I gave a lecture, I would always start by saying that people can call me by my name (Andy), or they can choose to use Dr Stapleton if they feel that is more appropriate.

In my experience, most academics will not mind if you call them by their first name and, in countries like Australia, it seems to be the most common way for students to interact with their teachers.

It is not uncommon for the opposite to be true – and, like I have mentioned above, always start with the formal interactions. It is likely that you will be invited to call the PhD holder by their first name.

Outside of a formal setting most PhD holders really don’t mind how you talk to them.

The things a PhD student needs to do to become a doctor

The reason a PhD can call themselves doctor is because they have been awarded the highest qualification possible in their field.

A PhD requires you to perform research and produce a thesis or dissertation. The new information must contribute significantly to the field and report novel and new findings.

The PhD thesis is examined by other experts in the field (known as peers) and these other experts are responsible for telling the university whether or not you have satisfied the criteria to become a PhD.

There are other, more modern, ways of reporting your findings including peer-reviewed journals and professional doctoral reports.

Either way, admission to a PhD requires many years of hard work and dedication to answering a unique and unanswered question in your field.

I think that this satisfies the original use of the term doctor and is a great accomplishment for anyone.

It’s hard work but with the right guidance and dedication it is achievable by almost anyone.

Wrapping up

This article has covered everything you need to know about whether a PhD is a doctor.

The original term was introduced in the 1300s to denote an imminent scholar. This scholar would teach and pass on information to their students.

In modern times, the term doctor has been used as an honorary title for other professional careers in recognition of the hard work that they have put in to achieve their position.

However, there are fears that the doctor title is slowly becoming used for too many health professional areas leading to confusion around who is a medical doctor and who has other health-related qualifications such as dentistry, naturopathy, and others.

Nonetheless, people without an understanding of the convention can still get confused between medical doctors and holders of a higher degree PhD.

What is a PhD?

  • Types of Doctorates
  • A Doctor of Philosophy (PhD) is the highest globally recognized postgraduate degree that higher education institutions can award.
  • PhDs are awarded to candidates who undertake original and extensive research in a particular field of study.
  • Full time PhD programmes typically last three to four years, whilst part time PhD programmes typically last six to seven years.
  • A PhD can lead to an academia teaching role or a career in research. A PhD can also equip you with skills suitable for a wide range of jobs unrelated to your research topic or academia.

Definition of a PhD – A Doctor of Philosophy (commonly abbreviated to PhD , Ph.D or a DPhil ) is a university research degree awarded from across a broad range of academic disciplines; in most countries, it is a terminal degree, i.e. the highest academic degree possible.

PhDs differ from undergraduate and master’s degrees in that PhDs are entirely research-based rather than involving taught modules (although doctoral training centres (DTCs) offer programmes that start with a year of lecture-based teaching to help develop your research skills prior to starting your project).

In most English-speaking countries, those that complete a PhD use the title “Doctor” (typically abbreviated to Dr) in front of their names and are referred to as such within academic and/or research settings. Those that work in fields outside of academia may decide not to use the formal doctor title but use post-nominal letters (e.g. John Smith PhD); it’s unusual though for someone to use both the Doctor title and post-nominal letters in their name.

PhD vs Doctorate

A PhD and a professional doctorate are both research-based terminal degrees.

However, where a PhD focuses on original research mostly around theoretical concepts, a professional doctorate focuses on examining existing knowledge to solve real-life, practical problems.

While there is much crossover between the two, a PhD is generally better suited for an individual to wants to advance the knowledge and understanding in their field, and a professional doctorate degree is better suited to a working professional who wants to better be able to apply knowledge and understanding to their field.

What Are the Entry Requirements for a PhD?

To be accepted on to a PhD programme, students usually need to hold at least a high ( 2:1 and above ) undergraduate degree that is related to the field of research that they want to pursue. A PhD candidate may also be expected to hold a Master’s degree , however, this does not mean you must have one, as it is still possible to enrol into a PhD without a Master’s .

Self-funded courses may sometimes be more relaxed in relation to entry requirements. It may be possible to be accepted onto a self-funded PhD programme with lower grades, though these students typically demonstrate their suitability for the role through professional work experience.

Whilst a distance learning project is possible , most PhD candidates will carry out their research over at least three years based at their university, with regular contact with two academic supervisors (primary and secondary). This is particularly the case for lab-based projects, however, some PhD projects require spending time on-site away from university (e.g. at a specialist research lab or at a collaborating institution abroad).

How Long Does a PhD Take?

Typically, full-time PhDs last 3-4 years and part-time PhDs last 6-7 years. However, at the discretion of the university, the thesis writing-up period can be extended by up to four years.

Although most doctoral programmes start in September or October, they are generally much more flexible than taught-courses and can start at any time of the year.

How Much Does a PhD Cost?

Tuition fees for UK and EU students vary between £3,000 and £6,000 per year, with the average tuition fee of £4,712 per year for 2023/24 programmes.

Tuition fees increase considerably for international students, varying between £16,000 to £25,000 per year, with an average tuition fee of £19,600 per year .

Nonetheless, most students will secure PhD funding in the form of studentships, scholarships and bursaries to help pay for these fees. These funding opportunities can either be partial, which cover tuition fees only, or full, which cover both tuition fees and living expenses.

UK national students can also apply for Doctoral Loans from Student Finance England if they are unable to secure funding.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

What Does a PhD Involve?

To be awarded a PhD, a doctoral student is required to produce a substantial body of work that adds new knowledge to their chosen field.

A PhD programme will typically involve four key stages:

Stage 1: Literature Review

The first year of a PhD involves attending regular meetings with your supervisors and carrying out a search on previously published work in your subject area. This search will be used to produce a literature review which should set the context of the project by explaining the foundation of what is currently known within the field of research, what recent developments have occurred, and where the gaps in knowledge are. In most cases, this will be an extension of your research proposal should you have produced one as part of your application. The literature review should conclude by outlining the overarching aims and objectives of the research project. This stage of setting achievable goals which are original and contribute to the field of research is an essential first step in a successful PhD.

The supervisor is the main point of contact through the duration of a PhD – but remember: they are there to mentor, not to teach, or do it for you . It will be your responsibility to plan, execute and monitor your own work as well as to identify gaps in your own knowledge and address them.

Stage 2: Research

The second year (and prehapse some of your third year) is when you work on your research. Having identified novel research questions from your review of the literature, this is where you collect your data to help answer these questions. How you do this will depend on the nature of your doctoral research: for example, you may design and run experiments in a lab alongside other PhD students or visit excavation sites in remote regions of the world. You should check in regularly with your supervisors to update them and run any ideas or issues past them.

Have the structure and chapters of your thesis in mind as you develop and tackle your research questions. Working with a view of publishing your work will be very valuable later on.

Stage 3: Write up of Thesis

The next key stage of a PhD is writing a doctoral thesis , which typically takes from anywhere between three months to one year. A thesis is a substantial body of work that describes the work and outcomes of the research over the previous two to three years. It should tell a detailed story of the PhD project – focusing on:

  • The motivations for the research questions identified from the literature review.
  • The methodologies used, results obtained, and a comprehensive analysis and discussion of the findings.
  • A detailed discussion of the key findings with an emphasis on the original contributions made to your field of research and how this has been impactful.

There is no universal rule for the length of a PhD thesis, but general guidelines set the word count between 80,000 to 100,000 words.

For your thesis to be successful, it needs to adequately defend your argument and provide a unique or increased insight into your field that was not previously available.

Stage 4: Attending the Viva

A viva voce , most commonly referred to as just a ‘ viva ‘, is an interview-style examination where the PhD student is required to engage in a critical appraisal of their work and defend their thesis against at least two examiners. The examiners will ask questions to check the PhD student has an in-depth understanding of the ideas and theories proposed in their thesis, and whether they have developed the research skills that would be expected of them.

The viva is one of the final steps in achieving a PhD, and typically lasts at least two hours, but this duration can vary depending on the examiners, the university and the PhD project itself.

Once you have done the viva – you’re on the home stretch. You will typically be asked to make some amendments to your thesis based on the examiner’s feedback. You are then ready to submit your final thesis for either:

  • PhD – If you pass the requirements you will be awarded a PhD degree (most common outcome),
  • MPhil – If you failed to meet requirements for a PhD, you may be downgraded to an MPhil degree (uncommon outcome),
  • Fail – No award is given, typically for cases of plagiarism (extremely uncommon outcome).

What Is It Like to Undertake a PhD?

We’re often asked what it is like to undertake a PhD study. Unfortunately, this isn’t a simple answer to this question as every research project is different.

To help give insight into the life of a PhD student, we’ve interviewed PhD students at various stages of their programmes and put together a series of PhD Student Interviews . Check out the link to find out what a PhD is like and what advice they have to offer you.

What Are the Benefits of A PhD?

A PhD is the highest globally recognised postgraduate degree that higher education institutions can award. The degree, which is awarded to candidates who demonstrate original and independent research in a particular field of study, is not only invaluable in itself, but sets you up with invaluable skills and traits.

Career Opportunities

First, a PhD prepares you for a career in academia if you wish to continue in this area. This takes form as a career in the Higher Education sector, typically as a lecturer working their way to becoming a professor leading research on the subject you’ve studied and trained in.

Second, a PhD also enables the opportunity for landing a job in a research & development role outside of the academic environment. Examples of this include laboratory work for a private or third sector company, a governmental role and research for commercial and industrial applications.

Transferable Skills

Finally, in possessing a PhD degree, you can show to employers that you have vital skills that make you an asset to any company. Three examples of the transferable skills that you gain through a PhD are effective communication, time management, and report writing.

  • Communication – presenting your work in written and oral forms using journal papers and podium presentations, shows your ability to share complex ideas effectively and to those with less background knowledge than you. Communication is key in the professional environment, regardless of the job.
  • Time management – The ability to prioritise and organise tasks is a tremendous asset in the professional industry. A PhD holder can use their qualification to demonstrate that they are able to manage their time, arrange and follow a plan, and stick to deadlines.
  • Report writing – Condensing three years of work into a thesis demonstrates your ability to filter through massive amounts of information, identify the key points, and get these points across to the reader. The ability to ‘cut out the waffle’ or ‘get to the point’ is a huge asset in the professional industry.

Aside from the above, you also get to refer to yourself as a Doctor and add fancy initials after your name!

What Can I Do After a PhD?

One of the most desirable postdoctoral fields is working within independent Research and Development (R&D) labs and new emerging companies. Both industries, especially R&D labs, have dedicated groups of PhD graduates who lead research activities, design new products and take part in crucial strategic meetings. Not only is this a stimulating line of work, but the average salaries in R&D labs and emerging start-ups are lucrative. In comparison, an undergraduate with five years of experience within their given field will, on average, likely earn less than a new PhD graduate taking on a R&D position.

It’s a common misunderstanding that PhDs only opens the door for an academic career such as university lecturers and training providers. Although obtaining a PhD opens these doors, the opportunities extend far beyond educational roles. In fact, recent data from the UK’s Higher Education Statistics Agency (HESA) indicates only 23% of PhD graduates take a position in educational roles . This low percentage is primarily because PhD graduates have a wide range of skills that make them suitable for a broad spectrum of roles. This is being seen first hand by the increasing number of PhD graduates who are entering alternative roles such as research, writing, law and investment banking.

How Do I Find a PhD?

We appreciate that finding a PhD programme to undertake can be a relatively daunting process. According to Higher Education Student Statistics , over 22,000 PhDs were awarded in 2016/17 within the United Kingdom alone. Clearly there are a huge number of PhD programmes available. This can sometimes be confusing for prospective doctorates, particularly when different programmes are advertised in different places. Often, it is difficult to know where to look or where to even start. We’ve put together a list of useful sources to find the latest PhD programmes:

  • A great place to start is with our comprehensive and up-to-date database of available PhD positions .
  • Assuming you are still at university, speak to an existing PhD supervisor within your department.
  • Attend as many postgraduate open days as you can. Whilst there, speak to current PhD students and career advisors to get an awareness of what PhDs are on offer.
  • Visit the postgraduate section of university websites and the PhD Research Council section of the UKRI website.

Whom should we really call a “doctor”?

This is in response to the News article by Roger Collier. 1 These days many health professionals use the title “doctor.” Indeed, The Canadian Press Stylebook now decrees that the title of doctor should be reserved for physicians. Physicians, surgeons, dentists, chiropodists, university professors and, in some countries, pharmacists describe themselves as doctors. This raises the question — are they? To answer this question, one has to examine that title from both linguistic and historical standpoints.

The word doctor is derived from the Latin verb “docere,” meaning to teach, or a scholar. Only by special arrangement do any of the preceding professionals teach. Only university professors with a doctoral degree normally teach at a university. Historically speaking, the title doctor was invented in the Middle Ages to describe eminent scholars. These doctorates date back to the 1300s. Such people were accorded a lot of respect and prestige.

The PhD, or Doctor of Philosophy, is the highest graduate degree awarded by our universities.

Health professionals receive undergraduate degrees in medicine. These are professional degrees, and not really doctorates. The MD degree is not a part of graduate faculties at North American universities.

It has now become fashionable to award so-called Doctor of Law degrees to undergraduate law school graduates in the form of a Juris Doctor or JD degree, including at the University of Windsor. These, too, are merely undergraduate degrees.

Because of the respect and prestige, medical schools, particularly in Scotland, started to address their graduates as doctors in the 17th century. The argument was that graduates of such schools obtain a bachelor’s degree before joining medical school. There are problems with such logic, namely, a degree past a bachelor’s degree could potentially be a master’s degree, but not a doctoral degree.

A doctoral degree (PhD) is a degree that one earns after a master’s degree. A PhD entitles a person to use the title doctor. These are the social and physical scientists who conduct and evaluate published research. A PhD degree is normally obtained after six to eight years of hard work past the bachelor’s degree.

When we are asked in a physician’s or a dentist’s office what kind of doctor we are, we respond, “the real one.” We are the ones who teach the others.

We hope that this contribution helps in clearing up the confusion in the community about the title doctor.

The Canadian Press should change its policy and stylebook to reflect these facts and this history.

This contribution should not be construed as an attack on any professional or group of professionals. The main purpose here is to educate the public.

Ph.D. & Dr. rer. nat. - Different names for a doctoral degree

Written by Karla 22.06.2021

Previously, we wrote about being a researcher in Germany. Here, we will discuss doctoral degrees and some country-dependent differences.

Internationally, a doctoral degree can be awarded in any field of science. Depending on each doctoral program and the country where it is taking place, the time and requirements to graduate vary. In the majority of cases, a degree is awarded after delivering a written thesis summarizing the research and defending it in front of a panel of experts in the specific field or a committee involved in the research study from start until completion. If you are interested in pursuing a doctoral degree in natural sciences in Germany, you should know that German institutions may award either the title of Ph.D. or Dr. rer. nat. If you are new to the German system of higher education, you may wonder about the difference between Ph.D. and Dr. rer. nat. Here we’re gonna break it down for you.

What is a Ph.D.? The Doctor of Philosophy , better known for its abbreviation Ph.D., is a degree of postgraduate education awarded for an original research study where individuals have contributed to the understanding of a field. According to the author Keith Allan Noble, the first doctoral degree was conferred in Paris around the year 1150 (Noble, 1994). In the following centuries, the Ph.D. degree gained popularity and shaped into the highest academic degree worldwide.

Why Germany uses the Dr. rer. nat. title? In Germany, the doctoral degree is awarded after one completes the process known as “Promotion”, which ends with presenting the thesis dissertation to a committee. Rather than universally receiving the Ph.D. title, latin suffixes are used to specify the field of the doctoral degree awarded in Germany (Academic positions, 2018). This is why after completing a doctoral programme in natural sciences in Germany, the degree obtained is Dr. rer. nat. from the latin Doctor rerum naturalium , or doctor of natural sciences.

Here are some examples of different discipline-specific doctoral degrees that can be obtained at the Ludwig-Maximilians-University in Munich, depending of the field of study (LMU München, 2021): Dr. rer. nat. (natural sciences) Dr. phil. nat. (humanities and natural sciences) Dr. med. (human medicine) Dr. med. dent. (dental medicine) Dr. rer. biol. hum. (human biology)

Ph.D. or Dr. rer. nat. - Is there a difference? Ph.D. and Dr. rer. nat. are both recognized as doctoral degrees. As an example of this parallelism, the Max-Planck institute states that the Dr. rer. nat. degree awarded by the Faculty of Science at the University of Tübingen is the german equivalent to a Ph.D. (Max Planck Institute for Developmental Biology, 2021)

Some Universities give you the opportunity to choose between obtaining a Ph.D. or a Dr. rer. nat. title, which can arguably be confusing to foreigners pursuing a Ph.D. in Germany. Examples of those universities are the Freie Universität Berlin (Freie Universität Berlin, 2021) and the University of Ulm (Universität Ulm, 2020). This reinforces that a Dr. rer. nat. degree is equivalent to a Ph.D.

Nevertheless, keep in mind that you should be careful about what you call yourself in official documents in Germany. According to German regulations, if you have a Ph.D. title you are allowed to write your name as either “Name Surname, Ph.D.” or “Dr. Name Surname”. Conversely, if you have a Dr. rer. nat. title you can only use it like this or as “Dr. Name Surname”. Make sure to comply when writing any official documents!

The science of happiness

First-year students hone more than their research skills by exploring what it means to be happy

What is happiness, and why do we strive for it? Can we become happier? Should we? Is happiness a good thing? 

Dr. Megan McCarthy

Dr. Megan McCarthy (PhD ’16)

“ARTS 140 is really focused on becoming critical consumers of information and learning how to organize evidence to make a compelling argument,” McCarthy said.  

McCarthy designed the course to challenge students to think about their beliefs and understanding of happiness, research and test various perspectives on happiness and critically evaluate claims about it.   

But can students — or anyone — separate their personal and intuitive feelings about happiness to examine it critically?  

“I first ask the students to try to write their own definition of happiness,” McCarthy said. “And then they look at different definitions over different eras, fields and in different parts of the world. I get them to reflect on how their definition compares to other conceptions. And then we talk about the roles of empiricism, critical thinking and how looking at data can shape our understanding.”  

Having taught the course every term since 2021, McCarthy has found that, because students often come from different backgrounds, they engage in rich comparative discussions with classmates about their own beliefs and how their experiences led to those beliefs. Through these interactions, the students become “much more accepting of different ways of looking at the subject because they're exposed to different experiences. And they have a lot of fun.”  

I've had students talk to me about how the course has transformed their personal lives. — DR. MEGAN MCCARTHY  (PhD ’16)

As a practice-based course, the students are encouraged to test happiness-boosting claims and then reflect, discuss and evaluate them. In their main project, they even developed their own methods to increase happiness in the community, drawing from their primary research sources and interpretation of evidence.   

Student happiness projects included cooking dinner with their family to increase bonding, making and delivering care packages for unhoused people in the area and organizing a sharing circle in their university residence to reduce stress and enhance social connections.  

One student designed a happiness plan for their workplace after noticing employees weren’t working effectively as a team. They developed a method to strengthen the co-worker community and improve well-being. The student reported that their manager was planning to implement the changes in the workplace in the future.   

“I've had students tell me that the assignments have made them fall in love with research,” McCarthy said. “They get really excited about the process — how to come up with a research question, collect the data and think critically about it.”   

McCarthy sets specific learning outcomes for the course, which include being able to reflect critically on their own cultural experiences that shape how they feel. “I think that one is important because that can be applied across disciplines where they're learning to engage with the ideas and beliefs of others and understand their own assumptions. And I think that can support good relationships and community.”   

Becoming a better researcher is not the only positive outcome of the course. “I hear about it impacting emotional or social well-being,” McCarthy reflected. “I've had students talk to me about how the course has transformed their personal lives. That it has made them happier people, that it has made them think differently about the way they're engaging with and relating to other people. And that's tremendously powerful for me.”
