PhD is an abbreviation for Doctor of Philosophy. This is an academic or professional degree that qualifies the bearer in most countries to teach their chosen topic at the university level or to work in a specialised position in their chosen sector.
The term “philosophy” derives from the Ancient Greek “philosophia”, which translates literally to “love of wisdom.” It originally denoted a person who has completed a full general education on the fundamental issues confronting the contemporary world. The Doctor of Philosophy degree, although still involving a love of learning, is today awarded to those who have sought knowledge in a much more specific discipline.
A PhD is an internationally recognised postgraduate academic degree offered by universities and higher education organisations to a candidate who has completed considerable and unique research in their chosen subject. PhD degrees differ based on where you are located and what discipline you are pursuing. However, in general, the PhD is the highest degree a student may obtain (with some exceptions).
