Instructional Assistant Professor

Research Interests

I CURRENTLY STUDY THE PHYSICO-CHEMICAL PROPERTIES OF AEROSOLS BASED ON THEIR ABSORPTION OF LIGHT RANGING FROM THE SHORTWAVE TO INFRARED WAVELENGTHS USING AERONET, DOE ARM, AND SATELLITE DATA. MY FUTURE GOALS ARE TO (1) IMPROVE UPON EARLIER AEROSOL CLASSIFICATION METHODS BY USING THEORETICAL RADIATIVE TRANSFER CALCULATIONS, (2) ANALYZE THE LONG-TERM AEROSOL IMPACTS ON MARINE BOUNDARY LAYER AND DEEP CONVECTIVE CLOUD DEVELOPMENT AND (3) DISCERN POSSIBLE IMPACTS OF BIOMASS BURNING SMOKE ON SEVERE WEATHER AND LIGHTNING. I ALSO MENTOR FIVE UNDERGRADUATE STUDENTS WHO ARE CONDUCTING SUPERVISED RESEARCH ON TOPICS SUCH AS ARCTIC CLIMATE CHANGE, AEROSOL TRANSPORT, AND AEROSOL IMPACTS ON LARGE HAIL AND LIGHTNING.
