Back when our inventors Tim Stelzer, Mats Selen, Gary Gladding, and Benny Brown were building i>clicker in their garages, the goal was simple—they needed a response system that worked every single time the used it. i>clicker was sold to Macmillan in 2005; however, Tim Stelzer and Mats Selen remain key visionaries and active members of the product development team.

 

 

Timothy Stelzer

timothyStelzerTimothy Stelzer, Research Associate Professor of Physics received his bachelor’s degree in physics from St. John’s University in 1988, and his Ph.D. in physics from the University of Wisconsin-Madison in 1993. After working as a senior research assistant in the Center for Particle Theory at Durham University (UK), he joined the Department of Physics at the University of Illinois as a postdoctoral research associate in 1995. In 1998, he was promoted to a visiting assistant research professor and to an assistant research professor in 2000. He is currently a research associate professor with active research programs in both high energy physics and physics education research.

A high-energy particle theorist, Professor Stelzer has concentrated on standard model physics at hadron colliders and is best known for his development of MadGraph and MadEvent programs. These calculation tools are utilized by hundreds of physicists around the world for predicting the outcomes of collisions at Fermi National Accelerator Laboratory and the CERN Large Hadron Collider.

Fortunate timing allowed Professor Stelzer to participate in the reform of the introductory physics courses at the University of Illinois and the creation of the Physics Education Research group. The curriculum revision utilized the principles of active learning and peer instruction. Professor Stelzer has received many teaching awards and is a regular on the University’s “Incomplete List of Teachers Ranked as Excellent by Their Students.” His most prized recognition is being voted “Lecturer with the best sense of humor.” He is currently focusing on developing educational materials that fully exploit the new level of interactivity available in lecture.

Mats Selen

matsSelenMats Selen, Professor of Physics, earned a B.S. in physics from the University of Guelph (1982), an M.Sc. in physics from Guelph (1983), and an M.A. in physics from Princeton University in 1985. He received his Ph.D. in physics from Princeton in 1989. He was a research associate at the Cornell Electron Storage Ring (CESR) at Cornell University from 1989-1993. He joined the Department of Physics at Illinois in 1993 as an assistant professor, was promoted to associate professor in 1997, and to full professor in 2001.

Since coming to Illinois, Selen 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 developed Physics 123, a hands-on physics course taken by about 100 elementary education students each spring. He also started the Physics Van, an award-winning community outreach program that introduces grade school children to the fun and excitement of physics, and is a regular on local morning television as “The Whys Guy.”

As an experimental high-energy physicist, Professor Selen has made significant contributions in several research areas including the study of charmed meson production and decay, and the design and construction of high-speed electronics.
