Jeff is a research meteorologist and federal lead of the Doppler Radar and Remote Sensing Research team. His primary areas of research are (1) applications of polarimetric weather radar to cloud and precipitation microphysics as observed in nature and storm-scale numerical modeling and (2) studies of convective storm structure and evolution using real and simulated weather radar.

Before joining NSSL as a federal meteorologist in 2017, Jeff was a research scientist with the Cooperative Institute for Mesoscale Meteorological Studies (CIMMS) at the University of Oklahoma (2015-2017) and a post-doctoral research associate hosted by NSSL through the National Research Council's Research Associateship Program (NRC RAP; 2013-2015).
