Primary Research Area

- Ph.D. University of Wisconsin Madison 1993
Professor Timothy Stelzer 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.
A high-energy particle theorist, Professor Stelzer has concentrated on standard model physics at hadron colliders. He has written extensively on top-quark physics and radiation in top events. In addition, he has developed computational methods that have dramatically reduced the difficulty of performing complex cross section calculations. He is the primary author of MadGraph®, a software program that automatically generates the Feynman diagrams and helicity amplitude code for tree-level standard model processes. Most recently, he has been working on a new program to predict how often rare new particles would be produced and also what signatures would distinguish these new particles from the large background of particles already known. He has developed a novel multi-channel approach that efficiently integrates any scattering amplitude to obtain the cross section of any desired process.

Professor Stelzer is a founding member of the Physics Education Group at Illinois, where he focuses on the effective use of technology to improve student learning. His innovations include
- Mastery Inspired Online Activities
Based on the principles of mastery learning, these activities provide students a structured online environment to iteratively practice, assess and improve their understanding of physics.
- IOLab Wireless Lab System
IOLab is a low cost easy-to-use device that wirelessly transmits data from a myriad of sensors to a student’s laptop. This system allows students to obtain high precision data in and out of the laboratory.
- SmartPhysics Learning System
SmartPhysics includes a complete set of prelectures for introductory physics designed around multimedia learning. Clinical studies have shown these prelectures to be more effective than textbooks in helping students learn introductory physics and are used by thousands of students across the US every year. Several other disciplines are using this system to deliver their own material under the flipit series.
i>clicker is a wireless classroom polling system that has facilitated student-teacher interactions for millions of students around the world.
