Research Interests:

I have been working on various research projects involving topics such as microwave remote sensing, UHF wind profiler data processing and quality control. My most recent research includes Airborne Doppler radar data analysis and severe weather studies (tornadoes, supercells, fronts and drylines).

Currently I am in the convective weather group working on enhencing the autonowcaster using various data sets such as ASAP sattllite data, MM5 model data, etc.
