Pratt was an undergraduate student at Pennsylvania State University, where she originally majored in environmental science but eventually switched to chemistry.
[1] She moved to the University of California, San Diego for graduate studies, where she worked toward a doctorate in time of flight mass spectrometry.
[6] Primary atmospheric particles can originate from natural and human-made sources, which include sea spray, soot and bacteria.
[3] These undergo various reactions and can form secondary atmospheric particles, evolving into dynamical chemical mixtures such as aerosols.
[3] In 2018, she started a United States Department of Energy project to use single particle mass spectrometry during the Polar night.
