Kerri Pratt is an Associate Professor in the Departments of Chemistry and Earth & Environmental Sciences at the University of Michigan in Ann Arbor, Michigan, USA. She received her Ph.D. in Chemistry from the University of California, San Diego in 2009. From 2010-2013, she was a US National Oceanic & Atmospheric Administration Climate & Global Change Postdoctoral Fellow and US National Science Foundation Postdoctoral Fellow in Polar Regions Research in the Department of Chemistry at Purdue University. Her research program focuses on field measurements of the chemical interactions of atmospheric trace gases, particles, and snow in the Polar Regions and wintertime environments. In particular, her research group has made significant advances in understanding Arctic air-snow interactions, multiphase halogen chemistry, and aerosol sources and composition. Her group regularly conducts fieldwork in the Alaskan Arctic and has participated in several international Arctic icebreaker campaigns, as well as conducted fieldwork in Michigan and Maine. Dr. Pratt is the recipient of the 2021 American Meteorological Society Henry G. Houghton Award, 2018 US Department of Energy Early Career Award, 2018 American Chemical Society James J. Morgan Environmental Science & Technology Early Career Award, 2017 Sloan Research Fellowship in Chemistry, and the 2016 National Academy of Sciences Gulf Research Program Early Career Fellowship. She is an Editorial Board member of the journals ACS Earth & Space Chemistry and Analytical Chemistry. She has been a steering committee member of the IGAC activities CATCH (Cryosphere and Atmospheric Chemistry) and PACES (air Pollution in the Arctic: Climate, Environment, and Societies) since 2016 and 2017, respectively.
