PhD, or Doctor of Philosophy, refers to the postgraduate degrees that are awarded to candidates after completing the university program. There are a variety of disciplines in which candidates can earn a PhD and there are programs around the world that offer top-notch education facilitated by faculty that are experts in their field. PhD programs prepare candidates for careers in academia, research, government, or industry.

Requirements in PhD programs vary depending on the country, the university, and the program. Most PhD programs require a master’s degree, but some will accept candidates with only a bachelor’s. Most programs take a minimum of 3 or 4 years to complete and require a combination of coursework and research, and others will expect candidates to teach undergraduate courses as well as write publications. The bulk of most PhD programs lie in the candidate’s original research that leads to a dissertation or thesis of publishable quality, that provides significant contribution to the field, and that candidates must defend in front of a panel of experts.
