Atmospheric chemistry research in the Department of Chemistry at UC Irvine is focused on the fundamental chemistry of the air we breathe. Research in our program utilizes an interdisciplinary approach to understand and answer the most important issues in air pollution and climate change, and their impacts on human health and well-being. Our research encompasses a broad set of approaches that include spectroscopic and computational methods, gas phase chemistry, multi-phase studies on aerosol particles, field measurements of gases and particles, and modeling of chemical processes across a broad range of temporal and spatial scales. Students and Postdoctoral Scholars learn concepts and techniques across many disciplines to develop the skills necessary to tackle these global challenges to our environment and health. The research currently involves close collaborations within the School of Physical Sciences and with researchers in the Schools of Medicine and Engineering, as well as with Department of Energy National Laboratories and a number of international researchers.
