Education:

• B.S., University of Southampton, U.K.
• Ph.D., University of Southampton, U.K.

Areas of Expertise:

• Atmospheric Chemistry and Air Quality

Research Interests:

• Current research interests are focused on air quality and atmospheric chemistry issues associated with the relationship of aerosol composition to its optical properties. Experimental studies, using the Wyoming King Air research aircraft, have investigated the physical, chemical, and optical characteristics of the atmospheric aerosol as well as the distribution of aerosol precursor trace gases, in both clean and polluted tropospheric environments. Aerosol mass spectrometry is now being used to advance these investigations. Previous studies have concentrated on evaluations of the budgetary cycles of trace gases that influence global climate change and/or stratospheric ozone, the distribution of stratospheric ozone as observed by the CLAES instrument on board the Upper Atmosphere Research Satellite, cloud water and raindrop chemistry, especially on supercooled clouds, the scavenging of trace species by precipitation, and ice crystal and crystal aggregate growth mechanisms. Other research interests have included photochemical transformations of inorganic and organic gaseous species, especially those involving triplet biradicals.
