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!

Michigan Geophysical Union Poster Session

This past Monday, Pratt lab graduate student Eric Boone and undergraduates Jill Cellini, Wuliang Zheng and Zhuoyu Peng took part in the Michigan Geophysical Union (MGU) poster session. MGU is a great organization that allows many types of environmental researchers to display their work with their peers. Our group presented our current work on aerosol and cloud interactions in the southeast United States, particle growth events in the Arctic, and chemical analysis of cloud water from Whiteface Mountain (quite the diverse subject matter!). The session was very exciting, with many good discussions with researchers and faculty. In addition, Eric was honored to have his poster judged as 1st place in the Atmospheric and Climate Sciences category!

Shipping snow from Barrow to Michigan

Research in Arctic is an adventure.  Lucky for us Alaska Airlines flies all of the way to Barrow, AK.  This time my flight itinerary was Detroit, MI to Chicago, IL to Seattle, WA to Fairbanks, AK to Deadhorse/Prudhoe Bay, AK to Barrow, AK and back via Barrow, AK to Fairbanks, AK to Seattle, WA to Detroit, MI!  The airport "terminal" in Barrow, AK consist of one room with a baggage claim "slide".  Luggage arriving in Barrow consists of lots of large boxes and coolers since there are no roads to Barrow!  My luggage included three bags/boxes with aerosol sampling equipment and three coolers for snow samples.  Two of my coolers have lots of insulation to prevent the snow from melting and are even bear-proof (which means that so far they haven't gotten damaged from all of the shipping, unlike the regular cooler)!
