Andrew Ault is a Professor of Chemistry in the College of Literature Sciences and the Arts at the University of Michigan. Andrew is an expert in the fields of analytical and physical chemistry, with a focus on the environment. Systems of interest include aerosol, surfaces, interfaces, and engineered nanoparticles, with a focus on their impacts on climate and human health. His research makes use of a wide array of analytical instrumentation, including Raman microspectroscopy, atomic force microscopy (AFM), photothermal infrared spectroscopy, electron microscopy, and single particle mass spectrometry. 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 undergraduate courses in analytical chemistry and has taught graduate courses in environmental chemistry and aerosol chemistry and physics. He has received a National Science Foundation (NSF) CAREER award from the Chemistry Division, a Sloan Research Fellowship in Chemistry (2018), was selected to the "Top 40 Under 40" power list by the Analytical Scientist (2018 and 2022), and was selected to the "40 Under 40" Recognition Program for Rising Stars in Environmental Engineering and Science by the American Academy of Environmental Engineers and Scientists (AAEES). In 2024 he was named a "Planet Protector" by the Analytical Scientist. In 2025 he was selected as a Fulbright Scholar to Australia, where he worked at the University of Wollongong. He is currently the vice-president elect of the American Association for Aerosol Research (AAAR), after previously serving on the board of directors from 2021-2024 and the working group chair for Aerosol Chemistry (2017-2018). He is also a member of the American Chemical Society (ACS) and other professional organizations.
