Nick Barber completed the last requirement for his doctoral degree by successfully defending his dissertation this morning. Committee members included Bob Marquis, Bob Ricklefs, Jon Chase, and Patty Parker. No headgear was needed, thankfully, and Nick gladly brought the pizza to the celebration party. Nick and his family have recently moved to the University of Massachusetts-Amherst, where he is starting a prestigious postdoc with Dr. Lynn Adler.
