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!

Upcoming joint Swedish-US Arctic cruise - press release and video!

Prof. Pratt is the lead PI of a team of researchers, including Prof. Patricia Matrai (Bigelow Laboratory for Ocean Sciences), Prof. Amanda Grannas (Villanova Univ.), and Prof. Andrew Ault (Univ. of Michigan), to study primary marine aerosol production in the high Arctic summer! We are one of four US teams funded by that National Science Foundation for the joint Swedish-US cruise to high Arctic aboard the icebreaker Oden during Aug. - Sept. 2018! This cruise, known as "Arctic Ocean 2018" and "MOCCHA: Microbiology-Ocean-Cloud Coupling in the High Arctic"

Prof. Pratt co-organizes ALPACA Workshop in Fairbanks, AK

Prof. Pratt co-organized the ALPACA (Alaskan Pollution and Chemical Analysis) Workshop, held in Fairbanks, Alaska from May 14-16, 2018. Prof. Pratt spoke in her role as a working group co-chair of the IGAC (International Global Atmospheric Chemistry) Project activity PACES (Air Pollution in the Arctic: Climate, Environment, and Societies), which sponsored the event, with NSF and IASC (International Arctic Science Committee).
