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!

Arctic bromine paper published!

Congratulations to Pratt lab postdoc Peter Peterson for his paper detailing the first observations of reactions on aerosol particles enabling the transport of reactive bromine aloft (decoupled from the snow surface)! "Observations of bromine monoxide transport in the Arctic sustained on aerosol particles was recently published in Atmospheric Chemistry and Physics. Please check out the paper!

Prof. Pratt receives college teaching award!

Prof. Kerri Pratt was awarded the 2017 Individual Award for Outstanding Contributions to Undergraduate Education from the University of Michigan College of Literature, Science, and the Arts! Nominations for this award are eligible from all levels of teaching faculty in the college (not just junior faculty), so this is super rewarding. This award to Prof. Pratt recognizes "novel opportunities for learning through authentic research experiences" in our newly developed general chemistry laboratory course! Together Prof. Pratt and PhD students Nate May and Stephen McNamara have now each won teaching awards for our development of this new snow chemistry research course!

Welcome Nour and Jia!

Welcome Nour Abduljalil and Jia Shi for the summer! Nour is a junior Chemistry undergraduate student at Towson University in Maryland and joined the Pratt lab this summer as a Chemistry REU participant!  Jia is an incoming Chemistry graduate student completing a summer rotation in the Pratt Lab. He is a former McNair scholar who recently graduated with a B.A. in Chemistry from St. Olaf College. We are excited for you both to be in the lab this summer!

Pratt Lab at the 2017 Canadian Chemistry Conference

Prof. Kerri Pratt, along with post-docs Dr. Peter Peterson and Dr. Siyuan Wang and Ph.D. students Matt Gunsch and Rachel Kirpes, presented their results from a number of different Arctic research projects currently ongoing in the group! The 2017 Canadian Chemistry Conference was a week-long conference in Toronto, Canada (May 28- June 1st, 2017) that attracted thousands of chemists to share their work and engage in productive discussions. It was great opportunity to network and touch base with many of our collaborators! The following presentations were given by Pratt Lab members:

Prof. Kerri Pratt: Invited talk, "Snowpack Molecular Halogen Production in the Springtime Arctic" highlighting our Arctic halogen measurements and modeling. 


Dr. Peter Peterson: Talk: "Comparison of Bromine Processes Over Coastal and Inland Arctic Snowpacks" featured airborne reactive bromine measurements collected during the BROMEX 2012 study near Utqiagvik (Barrow), AK.


















Dr. Siyuan Wang: Talk: "Snowpack Emissions of Cl2 and its Fate in the Arctic Boundary Layer: A Modeling Study" highlighted modeling studies of Cl2 emissions from Arctic snowpacks.


















Matt Gunsch: Talk: "Chemical Characterization of Atmospheric Particulate Matter within the Prudhoe Bay Oilfields, Alaska" featured results from our 2016 summer field study in the Prudhoe Bay oil fields of Alaska's North Slope
















Rachel Kirpes: Poster: "Influence of Secondary Sulfate on Arctic Sea Spray Aerosol and Organic Aerosol Mixing States during Winter and Spring" featured single particle analysis from our 2014 field study near Utqiagvik (Barrow), AK.
















We also took advantage of a free evening to check out a Blue Jays game!
