Dusan Zrnic is the leader of the Doppler Radar and Remote Sensing Research at the National Severe Storms Laboratory (NSSL) as well as a senior scientist. He is also an adjunct professor of Meteorology and Electrical Engineering at the University of Oklahoma. After employment as a research and teaching assistant with the Charged Particle Research Laboratory at the University of Illinois, he joined the Electrical Engineering Department of the California State University, Northridge, CA in 1969. He became associate professor in 1974 and professor in 1978. During the 1973--1974 academic year, Dr. Zrnic was a National Research Council postdoctoral fellow at the NSSL, and in 1975--1976, he was on sabbatical research leave from California State University at the same laboratory. His research experience includes circuit design, applied mathematics, magnetohydrodynamics, radar signal processing, and systems design. Recently, he has spent considerable effort toward improvements of weather radar signal processing, advancements of polarimetric measurements and their interpretation, and development of algorithms for NEXRAD.
