Biography
Dr. Ajit Singh specializes in river and lake hydrology, surface and groundwater resources sustainability, paleohydrology for flood risk and hazard assessment, and artificial and rainfall recharge. He earned his Ph.D. in Earth Sciences from IIT Kanpur in 2014. His research provided evidence of the legendary Saraswati River's past existence and its connection to the Harappan civilization, utilizing techniques like geophysical surveys, sediment coring, and isotopic analysis. Dr. Singh's postdoctoral work at Imperial College London examined groundwater structure and dynamics in NW India, publishing significant findings in peer-reviewed journals. His second postdoctoral stint at IIT Gandhinagar, in collaboration with the Archaeological Sciences Center, focused on the tectonic-geomorphic study of Himalayan foothill rivers, revealing their role in supporting ancient civilizations.
