Dr. Trapp is a Professor with 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.

Research Interests

Dr. Trapp's research interests include the dynamics and observations of mesoscale convective systems, severe thunderstorms, and tornadoes; mesoscale modeling and predictability.
