A PhD (short for Doctor of Philosophy) is the highest academic degree. It make you an expert in your subject and you can use the title Dr. after your name. To get a PhD you do a lot of research and you write a big project called a thesis or dissertation — this project should add new ideas to your field. 

What is PhD

People who want to be university professors or researchers normally need a PhD. Some places call the same degree DPhil (this is more used in the UK, for example at Oxford). There is no higher degree after a PhD. After finishing, some people start working, some do another degree, and many do postdoctoral work (a postdoc) to get more research experience.

Around the world, PhD holders are known as "doctors" and are seen as experts. They can do independent or team research, write papers, and share findings with engineers, medical people, psychologists and others.

What is Meant by a PhD Degree?

A Doctor of Philosophy (PhD) is the highest academic degree that can be pursued only after the completion of a master’s degree in a specific field. It requires extensive research and a dissertation that contributes original knowledge. The term "philosophy" in this context refers to the pursuit of knowledge and wisdom, rather than the academic discipline of philosophy.

During the course of a PhD program, a doctoral candidate is required to submit a thesis statement alongside their dissertation, which usually encompasses a considerable amount of original research that is often regarded as suitable for publication in a peer-reviewed journal. In many countries, the candidate is also required to defend their work before a panel of expert examiners appointed by the university.

The PhD degree is awarded by higher and authorised institutions only after the successful thesis or dissertation. A PhD degree is typically pursued by those students who wish to settle in an academic or research field or students who wish to get a strong hold on their subject, as much as possible. A PhD degree can pose numerous challenges in front of a student, but equally rewards them for their determination and hard work. One may even be able to bring out some groundbreaking results during their journey to manifesting their highest academic degree.

The elements of getting a PhD involve:

  • Coursework: Completing required courses related to the chosen field.
  • Research: Conducting original research and writing a dissertation.
  • Defense: Defending the dissertation before a panel of experts.
