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.
