Research Abstract
The Earth's atmosphere can be viewed as an enormous reaction vessel where thousands of different physicochemical processes take place in a highly inhomogeneous and dynamic environment. Some of these processes are beautifully simple, such as splitting of oxygen molecules into individual atoms by ultraviolet photons. Others are rather involved chains of reactions, such as formation of photochemical smog in oxidation of volatile organics emitted by traffic and industrial sources. As life on our planet hinges on the stability of the delicate atmospheric environment, our group, together with other atmospheric scientists around the world, strives to understand both the fundamental mechanisms of atmospheric reactions and the adverse impacts of anthropogenic activities on the atmosphere.

We are especially interested in the mechanisms of photochemical interactions between the solar radiation and atmospheric aerosol particles. Can aerosol particles serve as efficient catalysts of photochemical processes? What sort of chemistry happens inside these particles as they drift through the atmosphere exposed to solar radiation? Can photochemical reactions on particle surfaces make the particles more toxic? How do these reactions affect cloud condensation properties of aerosol particles? In our laboratory, we try to find answers to these and to many other intriguing problems using modern analytical techniques based on laser spectroscopy, chromatography, and mass-spectrometry.
