Research scientist's deg. (3)

I believe the answer is:

phd

(Other definitions for phd that I've seen before include "Letters denoting holder of university doctorate" , "In brief, top university qualification" , "Initially a top university degree" , "Highest university degree" .)

I've seen this clue in The New York Times.
