Alumni

Members of our laboratory group include Postdoctoral Associates, PhD students, MSME students, and undergraduates.  A major emphasis of the lab group is making sure that all students (and post-doctoral associates), after graduation, find a position in academia or industry that they are excited about.  Laboratory PhD, MSME, and Postdoctoral Alumni are noted below.  For the PhD and Postdoctoral alumni, their current positions are listed.  For the MSME alumni, their positions immediately subsequent to graduation are listed (many have moved on the other companies or positions).  More than 50 undergraduate students have worked in the lab since 2009.
