Professor Mats Selen received bachelor's degree in physics from the University of Guelph (1982), a M.Sc. in physics from Guelph (1983), and an M.A. in physics from Princeton University (1985). He received his Ph.D. in physics from Princeton (1989). He was a research associate at the Laboratory for Elementary Particle Physics (LEPP) at Cornell University from 1989-1993. He joined the Department of Physics at Illinois in 1993 as an assistant professor and, since 2001, has been a full professor. He was named a Fellow of the American Physical Society in 2006 for his contributions to particle physics. Since arriving at Illinois, he has been a prime mover behind the massive curriculum revision of the calculus-based introductory physics courses (Physics 211-214), and he was the first lecturer in the new sequence. He created an undergraduate "discovery" course where freshmen create their own physics demonstrations, and developed the Physics Van Outreach program, in which physicists visit elementary schools to share enthusiasm for science). Professor Selen played a key role in the development of i>clicker™.
