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!

ATOFMS from Clarkson University!

While at the Atmospheric Chemistry Gordon Research Conference in July, Prof. Kerri Pratt and Prof. Andy Ault had a fantastic discussion with Prof. Philip Hopke at Clarkson University that led to our recent trip to Potsdam, NY!  Prof. Hopke is the Bayard D. Clarkson Distinguished Professor and the director of the Clarkson University Center for Air Resources Engineering & Science and Institute for a Sustainable Environment.
 
Prof. Hopke is graciously loaning us his aerosol time-of-flight mass spectrometer (ATOFMS) for the real-time measurement of the size and chemistry of individual atmospheric particles.  During the trip, Prof. Pratt and Prof. Ault also met with many fantastic engineering faculty whose research focuses on atmospheric particles relating to human health and air quality, and gave seminars in the Department of Civil & Environmental Engineering.

Beautiful fall colors in Potsdam, NY from the view of our rental box truck.

Getting ready to drive back to Michigan - Prof. Kerri Pratt with the ATOFMS in the box truck.

Thank you very much Prof. Phil Hopke!  We are incredibly grateful for your generosity!

Congrats to Jennifer!


Congratulations to Pratt lab undergraduate researcher Jennifer Berry who was accepted into the EcoQuest program to study abroad in New Zealand for the winter 2014 semester!  She will conduct field research toward her University of Michigan Program in the Environment major.  We will miss you and look forward to you coming back to us in the spring!  We wish you a safe and fantastic trip!
