Recent developments in the field of mass spectrometry are leading to molecular-level understanding of environmental chemistry issues, particularly for air quality and climate change. Our efforts are focused on three main techniques: 1) chemical ionization mass spectrometry, for real-time identification and quantitation of trace halogen-containing gases, 2) nano-desorption electrospray ionization mass spectrometry, for the determination of the molecular composition of atmospheric organic particles, and 3) aerosol time-of-flight mass spectrometry, for the measurement of the size and chemical composition of individual atmospheric nanoparticles in real-time. I will discuss examples of how these novel techniques are advancing the field of atmospheric chemistry.
Prof. Kerri Pratt received her B.S. in Chemistry from Penn State University and her Ph.D. in Chemistry from the University of California, San Diego with Prof. Kimberly Prather. She then completed post-doctoral research in the lab of Prof. Paul Shepson at Purdue University. Dr. Pratt joined the Department of Chemistry at the University of Michigan as an assistant professor in 2013. Her research focuses on the application of mass spectrometry to studies of environmental chemistry, with emphasis on understanding impacts of climate change in the Arctic. She has already published over 30 peer-reviewed papers and has funding from NSF, NOAA, and NASA. Currently, her group is conducting a fieldwork in the Arctic which involves deployment of a chemical ionization mass spectrometer to a tundra site!
