Cloud and aerosol physics
Combined experimental and theoretical research in the fields of nucleation, water microphysics, and aerosol science. Combustion aerosol studies have involved the environmental effects of gas turbine and rocket engines and have led to sampling campaigns at ground-based industrial sites and in the upper atmosphere. Recent work has focused on measurement techniques to support jet engine certification requirements.
