Biography

Piyush is currently a NASA Postdoctoral Program Fellow and engages in developing a novel retrieval approach for cloud condensation nuclei (CCN) concentrations using space-borne lidar techniques. Piyush’s research focuses on analyzing satellite observations to understand processes associated with aerosol-cloud interactions and their feedback mechanism. Prior to joining JPL, He was a Postdoctoral Fellow at Physical Research Laboratory (PRL), India, and worked on a multi-satellite approach to study the role of dynamics in aerosol-cloud interactions. He was a research scholar in Space Applications Centre, ISRO, India, where he was engaged with post-launch calibration of optical satellite and airborne sensors (i.e., INSAT-3D, INSAT-3DR, AVIRIS-NG). Simultaneously, he received his Ph.D. on aerosol-cloud interaction and its radiative implications using multi-satellite observations.
