Dr. Shantanu Jathar

Laboratory for Air Quality Research

Associate Professor

Mechanical Engineering

Dr. Jathar is an Associate Professor of Mechanical Engineering at Colorado State University (CSU). His research interests lie at the intersection of energy and the environment and at CSU he leads the Laboratory for Air Quality Research. He and his research group leverage laboratory experiments, field measurements, and numerical models to study the emissions, evolution, and properties of fine particles (or aerosols) arising from energy and combustion sources. Current research projects range from studying the photochemical evolution of organic compounds in wildfire plumes to improving chemical mechanisms of organic aerosols in chemistry-climate models. 
He has a B.S. in Mechanical Engineering from the Government College of Engineering Pune, an M.S. in Mechanical Engineering from the University of Minnesota, and a Ph.D. in Engineering and Public Policy from Carnegie Mellon University. Additionally, he also worked as a postdoctoral scholar in Civil and Environmental Engineering at the University of California Davis. He has received more than $1.2 million in research funding as a lead investigator through NOAA, DOE, EPA, and the state of Colorado and an additional $2 million as co-investigator through EPA, NSF, and NASA. He has published more than 40 manuscripts in journals including Science, Nature, and PNAS.
