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!
Congratulations to senior undergrads Anna Leemon and Annie Barget on their graduations from the University of Michigan!! Anna graduated with a B.S. degree in Chemistry and will be joining the Stanford University Teacher Education Program in the fall to earn a M.S. in Education to teach high school chemistry! Annie graduated with a B.S. degree in Biomolecular Science and will be continuing research with us this summer as a Michigan Space Grant Fellow! Congratulations! We are so proud!
Congratulations to Pratt Lab undergraduate students Alexa Watson, Claire Mattson, Logan Vear, and Maddie Parks who were all awarded HHMI summer research fellowships to continue research in the Pratt Lab! These fellowships were for alumni of the HHMI-sponsored Authentic Research Connection.
Earlier this month, Pratt Lab graduate student Rachel Kirpes was sponsored by the American Geophysical Union (AGU) to attend the AAAS Catalyzing Advocacy for Science and Engineering (CASE) workshop in Washington, D.C. To read more about what she learned from this experience, check out her post on AGU's science and policy blog, The Bridge!
I (Stephen) gave a presentation about research in the Pratt Lab to regional elementary and middle school students participating in the "You Be the Chemist" Challenge held at the University of Michigan on March 23rd. This event, put on by local firm PVS Chemical, is part of a national program in which 5-8 grade students participate in a chemistry academic challenge, similar to a quiz bowl, supported by local industry and academic institutions. For more information, visit their website!
Before the competition, the students learned about research at UM through presentations and demonstrations by lab groups in the Chemistry department. It was a great opportunity for students to see what a career in chemistry research would look like!
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!
