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!

Pratt Lab presents research at the Michigan Geophysical Union meeting

At the 14th Annual Michigan Geophysical Union meeting, six graduate students and five undergraduate students from the Pratt Lab presented their research. The topics highlighted the diversity of research that we are pursuing in our group. PhD student Matt Gunsch won first place in the Chemistry Section for his research on "Chemical Characterization of Atmospheric Particulate Matter from Prudhoe Bay, Alaska" and PhD rotation student Nicole Olson won second place in the Chemistry section for "Single Particle Analysis of Ambient and Laboratory Generated Lake Spray Aerosols". Senior Annie Barget won first place for the Michigan Geophysical Union Undergraduate category for her work on "Effects of Wind Speed and Sea Ice Conditions on the Chemical Composition of Coastal Arctic Snow". Congratulations to everyone who presented!

    No matter what we are live22 baccarat looking for, everything that happens in the game. Online casinos have not made much progress in the pursuit of victory, but we http://site-2197156-5826-5059.mystrikingly.com/ need to design what it does and how it works.
