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 atmospheric trace gases, particles, snow, and clouds and their interactions with the biosphere (forests) and cryosphere (snow and sea ice). Our interdisciplinary research has relevance to climate change, air quality, and human health. As an analytical chemistry lab, we primarily use novel mass spectrometry techniques during our field research. We invite you to follow our adventures in (and outside!) the lab!

Pratt Lab members at the American Geophysical Union meeting

Prof. Kerri Pratt, post-doc Dr. Peter Peterson, and Ph.D. student Matt Gunsch presented Arctic research results at the 2015 American Geophysical Union meeting held in San Francisco from Dec. 14-18. It was a productive, Arctic-focused meeting for us!

Prof. Pratt presented a poster titled "Single-Particle Chemical Composition in the Arctic during the Winter-Spring Transition" highlighting work by Ph.D. student Rachel Kirpes. She also gave an invited talk titled "Arctic Ozone and Bromine Chemistry: Relationships with Snow Composition and Open Lead Presence", based on work by post-doc Peter Peterson and undergraduate student Mark Hartwig through our NASA grant.

Post-doc Dr. Peter Peterson presented a poster titled "Characterizing Variability in the Spatial Distribution of Bromine Explosion Events in the Vicinity of Barrow, Alaska" based on his work through our NASA grant.

Ph.D. student Matt Gunsch presented a poster titled "Size-Resolved Chemical Analysis of Individual Atmospheric Aerosols near Barrow, Alaska" based on his work through our NOAA grant.

CHEM 125/126 - Snow Chemistry Poster Session Wednesday

The semester poster session for CHEM 125/126, section 400 (General Chemistry Laboratory - Authentic Research Experience in Snow Chemistry), will be Wed Dec 10 from 2:20-4:00 pm in the lower atrium of the Chemistry building. 28 freshman and sophomore undergraduate students will be presenting individual research posters about Arctic snow chemical composition and atmospheric impacts! Posters will be judged by UM Department of Chemistry faculty, post-docs, and graduate students from CSIE-UM. This course was developed by Prof. Pratt with funding from the Howard Hughes Medical Institute through the University of Michigan Authentic Research Connection. The overaching goal of the course is to enhance STEM retention.  Notably, 77% of the class is female, with two students in the UM Comprehensive Studies Program.
