Dr. Trapp is a Professor and Head of the Department of Atmospheric Sciences at the University of Illinois at Urbana-Champaign. Before joining Illinois in 2014, he was a Professor in the Department of Earth and Atmospheric Sciences at Purdue University from 2003-2014, and a research scientist with the National Severe Storms Laboratory (through the Cooperative Institute for Mesoscale Meteorological Studies) in Norman, Oklahoma from 1996-2003. Four years of his tenure with NSSL were spent as a visiting scientist at the National Center for Atmospheric Research in Boulder, Colorado.
Dr. Trapp's research interests include the dynamics and observations of mesoscale convective systems, severe thunderstorms, and tornadoes; mesoscale modeling and predictability.
Trapp received his B.S. degree from the University of Missouri-Columbia, M.S. degree from Texas A&M University, and Ph.D. degree from the University of Oklahoma. He was a National Research Council Postdoctoral Fellow.
