Career Overview

Dr. Sonia M. Kreidenweis is a professor of atmospheric science at Colorado State University. She received her B.S. in chemical engineering from Manhattan College and her M.S. and Ph.D. in chemical engineering from the California Institute of Technology. Prior to joining CSU in 1991, she was an assistant professor in the Department of Chemical Engineering at San Jose State University and served as a consultant in aerosol and chemical interactions in the atmosphere at the Lawrence Livermore National Laboratory. Her research focuses on characterization of the physical, chemical, and optical properties of atmospheric particulate matter, and the effects of the atmospheric aerosol on visibility and climate. A particular focus area is the characterization of aerosol interactions with water vapor. She has conducted field studies in several U.S. national parks to establish the sources and characteristics of particulate matter responsible for visibility degradation, with a recent focus on the impacts of prescribed and wild fires. Ongoing laboratory and field studies have investigated the role of particles and of individual compounds found in particulate matter in the nucleation of cloud droplets and ice crystals, and the effects of aerosols on cloud microphysics, precipitation, and climate. Prof. Kreidenweis is a past president of the American Association for Aerosol Research and also served on the executive committee of the American Meteorological Society. She is a Fellow of the American Association for Aerosol Research, American Meteorological Society, and American Geophysical Union. She was named a University Distinguished Professor in 2014.
