Dr. Aatish is an Assistant Professor at the Indian Institute of technology Bhubaneswar.  His research interests include understanding trends in surface water-groundwater fluxes, surface-subsurface interactions, and the unsaturated zone. He is actively involved in developing tools like numerical models and machine learning to explore various hydrological flow and transport processes.

Previously he was a Post-Doc at the University of Alabama where he did research on groundwater recharge in snow affected areas. His mentor was Prof. Mukesh Kumar. Prior to that, he was a Post-Doc briefly at Indian Institute of technology Bombay. He earned his PhD from Indian Institute of technology Bombay under the supervision of Prof. T.I. Eldho. He developed meshfree numerical models which can simulate reactive transport in groundwater. He also has experience in runoff modelling during his Masters at Indian Institute of technology Bombay.
