Rajan Chakrabarty's research focuses on two distinct themes: (i) Investigating the role of atmospheric aerosols in earth’s energy balance using novel instrumentation and diagnostic techniques, and numerical models; and (ii) Understanding aerosol formation in combustion systems toward synthesis of high porosity and surface-area materials for energy applications.
In 2014, Professor Chakrabarty joined the faculty at Washington University in St. Louis. He operates the Aerosol Physics and Technology laboratory (APT Lab) in the Department of Energy, Environmental & Chemical Engineering. From 2011 to summer 2014, he served as an Assistant Research Professor at the University of Nevada-Reno/Desert Research Institute. He currently serves as the American Association for Aerosol Research (AAAR) Chair of the Aerosol Physics working group.
