Jeremy Perrin (class of 2013), one of Dr. De Pree's research alums, was recently announced as a finalist for the American Physical Society's prestigious Apker Award given for outstanding undergraduate research.  This Award is given annually to two students (one from a non-PhD granting institution and one from a PhD granting institution); only five finalists in each category are named each year.  The Apker Award is the highest honor in the physics community for undergraduate research and is given to students who "have demonstrated great potential for future scientific accomplishment."

Jeremy is now at Cornell University in Ithaca, New York pursuing a PhD in physics.
