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!

Eclipse 2017!

On August 21st, the Pratt and Ault labs took an afternoon break to see the near-total solar eclipse over Ann Arbor! Fortunately, the unpredictable Michigan weather cooperated enough to see the 80% coverage before storm clouds rolled in. We all had a great time joining the hundreds of people who gathered on the UM Diag to view this amazing event!

The cloud cover was just right to snap an unfiltered photo of the sun
