Kerri Pratt is an American chemist and Associate Professor of Chemistry at the University of Michigan. Her research considers atmospheric chemistry and how it impacts human health. She studies the interactions of atmospheric gases using mass spectrometry based techniques.
Early life and education
Pratt was an undergraduate student at Pennsylvania State University, where she originally majored in environmental science but eventually switched to chemistry.{{Cite journal|last=Lockwood|first=Deirdre|date=2020-04-22|title=A Conversation with Kerri Pratt|url=https://doi.org/10.1021/acscentsci.0c00379|journal=ACS Central Science|volume=6|issue=4|pages=448–449|doi=10.1021/acscentsci.0c00379|issn=2374-7943|pmc=7181312|pmid=32341989}} She moved to the University of California, San Diego for graduate studies, where she worked toward a doctorate in time of flight mass spectrometry.{{Cite book|last=Pratt|first=Kerri Anne|url=http://escholarship.org/uc/item/9r28v4g6|title=New insights into single-particle mixing state using aircraft aerosol time-of-flight mass spectrometry|date=2009|publisher=University of California, San Diego|isbn=978-1-109-36545-0|location=La Jolla|language=English|oclc=462090252}} Her doctoral research was supervised by Kimberly Prather. She was a postdoctoral researcher at Purdue University.{{Cite web|title=Kerri Pratt {{!}} U-M LSA Chemistry|url=https://lsa.umich.edu/chem/people/faculty/prattka.html|access-date=2021-12-18|website=lsa.umich.edu|language=en}}{{Cite web|title=Purdue University: Shepson Atmospheric Chemistry Group: Shepson Group Members|url=https://www.science.purdue.edu/shepson/people/index.html|access-date=2021-12-18|website=www.science.purdue.edu}}
Research and career
Pratt works in atmospheric chemistry. She was appointed to the faculty at the University of Michigan in 2013.{{Cite web|title=Kerri Pratt {{!}} IGAC|url=https://igacproject.org/people/kerri-pratt|access-date=2021-12-18|website=igacproject.org}} She is interested in various chemical reactions that occur in the environment, including those that occur between trace gases, in aqueous solutions and on surfaces.{{Cite web|title=Pratt Lab :: Environmental and Analytical Chemistry|url=http://prattlab.chem.lsa.umich.edu/research_v2.php|access-date=2021-12-18|website=prattlab.chem.lsa.umich.edu}} Primary atmospheric particles can originate from natural and human-made sources, which include sea spray, soot and bacteria. These undergo various reactions and can form secondary atmospheric particles, evolving into dynamical chemical mixtures such as aerosols.{{Cite web|last1=Sherburne|first1=Morgan|last2=Michigan|first2=University of|title=Harmful algal blooms can become airborne|url=https://phys.org/news/2018-01-algal-blooms-airborne.html|access-date=2021-12-18|website=phys.org|language=en}} These particles can take on a variety of different sizes, between 3 nm and 10 μm. Pratt investigates the interactions between trace gases and clouds using mass spectrometry. She is particularly interested in the atmospheric composition of winter environments, for example, in the Polar regions.{{Cite web|title=Dr. Kerri Pratt {{!}} Arctic Snow Photochemistry {{!}} CPAESS - Cooperative Programs for the Advancement of Earth System Science|url=https://cpaess.ucar.edu/dr-kerri-pratt-arctic-snow-photochemistry|access-date=2021-12-18|website=cpaess.ucar.edu|language=en}}{{Cite web|url=https://cen.acs.org/environment/atmospheric-chemistry/Tracking-air-quality-Arctic-atmosphere/98/i20 | title=Tracking air quality in the Arctic atmosphere |access-date=2021-12-18|website=cen.acs.org}} The Arctic is undergoing a rapid loss of sea ice.{{Cite web|date=2019-12-19|title=Open water in wintertime Arctic is changing its atmosphere|url=https://news.umich.edu/open-water-in-wintertime-arctic-is-changing-its-atmosphere/|access-date=2021-12-18|website=University of Michigan News|language=en-US}}
Pratt makes use of mass spectrometries to various degrees of sensitivity, for examples aerosol time-of-flight mass spectrometry (aerosols of 0.07 – 1.6 μm diameter), chemical ionization mass spectrometry (gases at sub parts per trillion) and ambient ion mass spectrometry. These results are combined with one-dimensional modelling to understand how atmospheric compositions as a function of altitude and time. She looks to establish the feedbacks between human-made emissions, aerosols and the Earth to better predict air quality. In 2018, she started a United States Department of Energy project to use single particle mass spectrometry during the Polar night.{{Cite web|title=DOE Early Career Award for Kerri Pratt {{!}} U-M LSA Chemistry|url=https://lsa.umich.edu/chem/news-events/all-news/search-news/doe-early-career-award-for-kerri-pratt.html|access-date=2021-12-18|website=lsa.umich.edu|language=en}} These measurements were combined with data collected from aerosol samples on the German icebreaker RV Polarstern.
