Piyush completed his Master in condensed matter physics. His Post Graduate Diploma is in remote sensing specialization in atmospheric science. Later, he found interest in atmospheric science especially in aerosols and its climatic impacts. He was a research scholar in Space Applications Centre, ISRO, India, where he was working on post-launch calibration of optical satellite and airborne sensors (INSAT-3D, INSAT-3DR and AVIRIS-NG) and he earned his PhD on satellite-based aerosol-cloud interaction and its impacts on radiative forcing. He was a Postdoctoral Fellow at Physical Research Laboratory (PRL), India and was working on how dynamics play role in the aerosol-cloud interactions using multi-satellite observations. Presently, he is NASA Postdoctoral Fellow at JPL. He got interest to make use of space-borne lidar techniques to retrieve number concentrations of cloud condensation nuclei (CCN) and study CCN-cloud interaction.
