Prof. Ault Selected to Analytical Scientist's "Top 40 Under 40" Power List

Each year the Analytical Scientist selects 40 scientists internationally for their "Power List", in 2018 focusing on scientists under the age of 40 making waves in analytical science.

The Power List 2018: Fab 40

"The Top 40 Under 40 Power List returns to celebrate the gifted young scientists making waves in analytical science. Here we present the rising stars of the field (in alphabetical order), as nominated by our readers and shortlisted by our independent judging panel."

Prof. Ault was chosen for his contribution to analytical measurements of atmospheric aerosols using spectroscopy. One of the comments of his nominators was "Andrew has quickly established himself as a leader in developing and applying spectroscopic methods to study atmospheric aerosols – critical for addressing global health and climate change."

Freshwater field sampling trip

PhD student Nicole Olson and rotator Madeline Cooke collected freshwater samples from sites all over Michigan including Lake St. Clair, Saginaw Bay, the Flint River, and Muskegon Lake. These samples will be used to generate lake spray aerosol in the lab and analyze for the presence of harmful algal bloom toxins and metals. Check out some of the pictures from our trip!

Nicole gives departmental seminar!

Nicole recently gave a seminar, titled Organic Aerosol Phase and Viscosity Changes after Multiphase Chemistry, to the analytical chemistry graduate students and faculty. This was Nicole's first oral presentation about her research towards understanding the physicochemical properties of organic aerosols after reaction with gas-phase species. This project is an ongoing collaboration with the Surratt Group at UNC-Chapel Hill. Congrats!
