Coty Jen is an assistant professor in the Department of Chemical Engineering and a member of the Center for Atmospheric Particle Studies at Carnegie Mellon University. Her research focuses on understanding how the chemical composition and physical properties of atmospheric aerosol particles influence air quality and climate. Specifically, her goal is to disentangle the chemical complexity of the atmosphere by measuring and then developing semi-empirical models to describe the numerous compounds and their reactions that help form and grow atmospheric particles. These models will help predict how human activities will alter air quality over the next few decades. In addition, Jen’s group specializes in developing novel aerosol measurement techniques to measure the physical characteristics and molecular make-up of atmospheric particles from several molecules to 2.5 µm in diameter produced from wildfires to complex atmospheric reactions.
Jen obtained her B.S. in chemical engineering at Columbia University in 2010, M.S. in chemical engineering at the University of Minnesota - Twin Cities in 2013, Ph.D. in mechanical engineering at the University of Minnesota - Twin Cities in 2015, and postdoc in environmental science, policy, and management at University of California, Berkeley in 2018. She received the NSF GRFP, NSF AGS Postdoctoral Fellowship, and the American Association of Aerosol Research Friedlander Award. Jen’s research is currently funded by NSF AGS Atmospheric Chemistry and DOE Atmospheric System Research.
