Andrew Ault is an Assistant Professor of Environmental Health Sciences in the School of Public Health and Assistant Professor of Chemistry in the College of Literature Sciences and the Arts at the University of Michigan. Andrew is an expert in the field of atmospheric chemistry, with a focus on aerosol and engineered nanoparticle impacts on human health and climate. His research makes use of a wide array of instrumentation to study the aerosol health and climate effects, with a focus on single particle mass spectrometry and Raman microspectroscopy. The Ault group utilizes an integrated approach involving field measurements, laboratory measurements on field samples, and laboratory measurements of well-characterized aerosol proxies. Andrew teaches a graduate course in environmental chemistry and special topics courses involving aerosols and atmospheric chemistry. He is a member the American Association for Aerosol Research (AAAR), American Chemical Society (ACS), and American Geophysical Union (AGU).
