Airborne Atmospheric Research (1987-present)
Assistant Professor (1998-present) Conducts independent and collaborative research on atmospheric aerosols, cloud physics, and cloud chemistry, using both field research and modeling. Current interests include the role and effects of condensed water in the atmosphere and the effect of aerosol particles on cloud microphysics and climate.
NCAR Scientist I and II (1994-1998) Supported the application of NCAR aircraft and instrumentation for research. Developed and monitored airborne aerosol and cloud microphysical measurement capabilities at RAF, including leading inlet flow modeling capability. Conducted independent and collaborative research on aerosols, cloud physics, and chemistry.
