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 aerosol growth paper published!

Congratulations to Pratt Lab post-doc Katie Kolesar, former undergraduate student Jillian Cellini, and post-doc Peter Peterson! Their paper details the first investigation of the occurrence and driving forces of aerosol growth events at Utqiaġvik (Barrow), Alaska and the finding of the importance of the Prudhoe Bay oilfields in this process. Check out "Effect of Prudhoe Bay emissions on atmospheric aerosol growth events observed in Utqiaġvik (Barrow), Alaska", published in Atmospheric Environment

Pratt Lab Participates in FEMMES Capstone Outreach Event

On Saturday, November 12th, members of the Pratt Lab volunteered for the capstone outreach event organized by FEMMES (Females Excelling More in Math, Engineering, and the Sciences), which invites middle school girls to the University of Michigan for a day of fun activities related to math, science, and engineering. The goal of this event is to engage girls from underrepresented groups in participating in STEM fields through hands-on demos and interactive presentations linked to actual research by a variety of groups on campus.

Our group hosted a series of fun- and somewhat messy- activities focused on climate change with links to atmospheric chemistry. Of course, it can sometimes be challenging to make our research relatable to a bunch of twelve-year-olds, so creativity and simplicity is key! We discussed ocean acidification through pop and lime, and greenhouse gases like carbon dioxide using acetic acid (vinegar), sodium bicarbonate (baking soda), and latex reaction vessels (balloons)! Overall, everyone had a great time and is looking forward to the next event in the spring!
