The overarching theme of my research is to develop a fundamental and quantitative understanding of the factors that determine the chemical composition of the atmosphere. I am particularly interested in delineating natural and anthropogenic impacts on the chemical composition of the atmosphere, and in exploring the potential for these impacts to affect natural ecosystems. My research involves the use of numerical models in conjunction with remote and insitu measurements of atmospheric composition.
