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!

Trip to Pacific Northwest National Laboratory

For two weeks in early January, graduate students Eric Boone (me) and Amy Bondy, accompanied by Professors Andrew Ault and Kerri Pratt, traveled to the Pacific Northwest National Laboratory Environmental Molecular Sciences Laboratory in Richland, WA. There we collaborated with Dr. Alex Laskin and Dr. Julia Laskin to examine aerosol, cloud water and rain water samples from the Southern Oxidants and Aerosol Study (SOAS), as well as cloud water from Whiteface Mountain in New York. The Pratt Lab utilized an Orbitrap mass spectrometer to get very detailed information about the chemical composition of the samples, also using a recently developed technique called nano-desorption electrospray ionization (nano-DESI).

We collected a huge amount of data and are very excited to begin looking through the results with the help of new lab undergraduates Wuliang and Zhuoyu! Thank you very much Dr. Alex Laskin and Dr. Julia Laskin for all of your help and for teaching us!
