Ph. D.

Highest academic credential

Ph.D. is the highest academic degree in most fields, short for Latin *philosophiae doctor* (doctor of philosophy).

The "philosophy" is historical—Ph.D.s are awarded across disciplines from physics to literature.

Earning one typically requires years of original research culminating in a dissertation: She's pursuing a Ph.D. in neuroscience.

Someone with this degree may be addressed as "Doctor."
