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!

Prof. Pratt receives DOE Early Career Award!

Prof. Pratt was chosen for a 2018 Department of Energy (DOE) Early Career Award! This funds the Pratt Lab to study Arctic aerosols during DOE ARM field campaigns in Nov.-Dec. 2018 (polar night) in Utqiagvik, Alaska and during the historic international MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) campaign aboard the German icebreaker Polarstern in the high Arctic from Sept. 2019 - Oct. 2020.

Jun and Jamy perform "surgery" on our ATOFMS!

Welcome to the Pratt Lab! Here are photos of new postdoc Dr. Jun Liu and PhD student Jamy Lee performing "surgery" on our aerosol time-of-flight mass spectrometer (ATOFMS) Maverick!


Welcome Dr. Jun Liu!

Welcome Dr. Jun Liu! Jun recently completed his PhD in Prof. Lynn Russell's group at Scripps Institution of Oceanography at the University of California, San Diego. He joined the Pratt Lab to learn single-particle mass spectrometry and study Arctic atmospheric aerosols!

New paper published inland sea spray and lake spray aerosol!

Congratulations to Pratt Lab PhD Dr. Nate May, as well as Pratt Lab PhD Dr. Matt Gunsch and PhD student Rachel Kirpes, for their paper published in Environmental Science & Technology Letter titled "Unexpected Contributions of Sea Spray and Lake Spray Aerosol to Inland Particulate Matter". We detected sea spray aerosol in northern Michigan from Hudson Bay, so don't always assume that Na+ is from dust in the summer!

Collaborator Prof. Ault gives radio interview about collaborative HAB aerosol research!

Collaborator Prof. Andrew Ault gave a NPR radio interview about our collaborative harmful algal bloom lake spray aerosol research! Enjoy listening!

Welcome Jamy, Kathryn, and Savannah!

Welcome Jamy Lee, Kathryn Kulju, and Savannah Haas! Jamy is a third-year Chemistry PhD student who is excited to join the Pratt Lab to pursue Arctic aerosol chemistry research! Kathryn is an incoming Chemistry graduate student completing a summer rotation in the Pratt Lab. Kathryn recently graduated with a B.S. in Chemistry from Northern Michigan University. Savannah is a junior Biochemistry undergraduate student at Villanova University and undergraduate researcher in our fantastic collaborator Prof. Amanda Grannas' lab. Savannah is participating in the University of Michigan Chemistry REU in the Pratt Lab! We are excited for all of you to be in the lab this summer!
