(Nashville, TN)  --  A former graduate student at Vanderbilt University is suing the school for sexual harassment and discrimination. 

The 20-million-dollar lawsuit claims a pattern of abuse from a supervising professor and says it continued even after it was reported.  According to the suit, the former student was subjected to sexually explicit jokes and innuendo, and was called fat, ugly and stupid in front of other students.  The former student reportedly left the program before earning her Ph.D. because of the abuse.
