Biography

Dr. Agniv Sengupta is a postdoctoral scholar at NASA's Jet Propulsion Laboratory. His interests broadly span across climate dynamics, hydroclimate variability, prediction, and predictability. A current focus of his research is on better understanding and predicting winter precipitation variations in the western United States. He is also interested in evaluating the representation of the global and regional water cycle in climate model simulations. Prior to joining JPL, he received his Ph.D. (2020) and M.S. (2016) in Atmospheric and Oceanic Science from the University of Maryland (UMD) at College Park. His doctoral research at UMD was focused on sea-surface temperature based statistical forecasting of the South-Southeast Asian summer monsoon rainfall distribution.
