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.

Short Biography
Sergey Nizkorodov was born in 1971 in Almaty, Kazakhstan. He received his undergraduate degree in biochemistry from Novosibirsk State University, Russia, in 1993 and graduate degree in physical chemistry from Basel University, Switzerland, in 1997. After doing his postdoctoral research in chemical kinetics and reaction dynamics at the University of Colorado at Boulder, and in atmospheric chemistry at the California Institute of Technology, he joined the faculty of the Department of Chemistry, University of California, Irvine (UCI) in 2002. He teaches general, analytical, and atmospheric chemistry courses at UCI, and does research on chemistry of particulate matter in the ambient atmosphere and in indoor environments using state-of-the-art spectroscopic and mass-spectrometric techniques. He has been a research mentor to over 100 graduate, undergraduate, high-school, and postdoctoral students with female researchers accounting for about 60% of this group. He has co-authored over 180 publications in peer-reviewed journals. He served as the President of the American Association for Aerosol Research (AAAR) in 2020-21, a professional organization of about 1000 scientists and engineers working to advance the field of aerosol research and technology, and been active in various service roles at UCI and in the research community.
