University Distinguished Professor Kreidenweis researches atmospheric chemistry in the troposphere involving aerosol-cloud-climate interactions and visibility.

Kreidenweis is a fellow of the American Geophysical Union, the American Meteorological Society and the American Association for Aerosol Research; she previously served as president of AAAR. She was recently elected to the National Academy of Engineering, “for elucidating the impact of aerosols on climate, linking chemical composition and cloud formation capacity.” She is co-lead of an NSF-sponsored Biology Integration Institute awarded to CSU BROADN, which is studying the microbiome of the atmosphere and its linkages to terrestrial sources of microbes.

Kreidenweis earned her B.S. in chemical engineering at Manhattan College in 1983. She then studied chemical engineering at the California Institute of Technology, completing her M.S. in 1985 and her Ph.D. in 1989.
