Coty Jen
Associate Professor, Chemical Engineering
Coty Jen is an associate 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 BS in chemical engineering at Columbia University in 2010, MS 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.

Biomedical Engineering Ph.D. student receives $49k grant award
BME’s Dhruv Bhattaram, a second-year Ph.D. student, received $49k from the NIH to advance research on the development and application of lung epithelial organoids called apical-out airway organoids (AoAOs). Bhattaram has been part of BME’s Charlie Ren’s group, and as PI, he will partner with ChemE’s Coty Jen, MechE’s Amir Barati Farimani, and Pitt’s Kong Chen to present AoAOs as a next-generation theragnostic platform targeted towards airway health and cilia pathophysiology.
