Atmospheric chemistry, Analytical chemistry

At present, the effects of atmospheric aerosols are the largest uncertainties in quantifying climate forcing due to man-made changes in the composition of the atmosphere. Aerosol particles can also have detrimental effects on human health, particularly people with respiratory illnesses and asthma. It has recently been established that significant amounts of particulate matter can be organic in nature, deriving from both primary and secondary sources. The oxidation of volatile organic compounds in the atmosphere leads to the formation of secondary organic aerosol. My research focuses on developing state of the art chromatographic and mass spectrometric techniques to study the composition of organic aerosols, a key method to understanding their formation and processing in the atmosphere.
