Past Graduate Students and Postdoctoral Associates

PAST GRADUATE STUDENTS
As a disciple of academic birth control, my graduate mentoring philosophy is to have few graduate students, typically four at a time, in whom I try to invest substantial effort.  I have been blessed with truly amazing students over the years, all of whom have touched my life in positive ways.  My past students in chronological order:
