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!

New paper showing harmful algal bloom incorporation into lake spray aerosol (ES&T cover feature!)

Congratulations to Pratt Lab PhD student Nate May for his new paper describing the incorporation of biological material into lake spray aerosol from wave-breaking on the Great Lakes. This paper "Aerosol Emissions from Great Lakes Harmful Algal Blooms" was recently published in Environmental Science & Technology and is highlighted on the journal's cover!
