Ph.D. is short for a doctor of philosophy degree. Although "philosophy" is in the title, the degree is not necessarily in the area of philosophy. Many students receive Ph.D.s in liberal arts subjects. A Ph.D. program usually consists of several years of study (depending on the program and pace of the student) in which the student must become an expert in the area of study and add to the body of knowledge in the area of study.
Individuals who earn a Ph.D. normally go on to work in research positions in their area of study. The Ph.D. program prepares you to enter the research field. Many Ph.D. holders pursue academic careers. Major universities often offer teaching positions to people who have this degree.
