Welcome to the Pratt Lab blog! Dr. Kerri Pratt is an assistant professor in the Departments of Chemistry and Earth & Environmental Sciences and faculty associate of the Program in the Environment at the University of Michigan. We study the chemical interactions of atmospheric trace gases, particles, clouds, and snow, with a focus on the Polar Regions and wintertime environments. Our interdisciplinary research has relevance to climate change, air quality, and human health. As an analytical chemistry lab, we primarily apply novel mass spectrometry techniques to our field research. We invite you to follow our adventures in (and outside!) the lab!

Arctic Molecular Iodine Paper Published in PNAS!

Prof. Kerri Pratt and PhD student Angela Raso (co-advised by Prof. Paul Shepson at Purdue Univ.) completed the first measurements of Arctic tropospheric I2, produced from the sunlit coastal snowpack. Read about "Active molecular iodine photochemistry in the Arctic" in the Proceedings of the National Academy of Sciences of the U.S.A.!
