Ph.D., 2006, University of Kentucky, USA; Postdoctoral, 2006-08, University of Texas at Austin; Physical Hydrogeologist, 2008-10, Alberta Geological Survey, Canada; Faculty, 2010-till, IIT Kharagpur
I work in groundwater exploration for suitable and sustainable drinking water sources in different parts of the world, specifically India.These study areas suffer from poor groundwater quality or groundwater insufficiency. With my specialization in regional hydrogeology and groundwater contaminant transport, my students and I are engaged in understanding decadal-scale groundwater storage changes over Indian subcontinent, groundwater-river-seawater interactions, groundwater quality evolution of the Ganges-Brahmaputra basin, Numerical and AI simulations of groundwater. I have also recently initiated a project on application of artificial intelligence techniques in predicting future groundwater availability and pollution in different parts of India.My regularly collaborators include internationally acclaimed scientists from NASA, U.S. Geological Survey, British Geological Survey, MIT, Columbia University, KTH Sweden, University College London, Manchester University etc.
My researches on groundwater have been funded by Ministry of Earth Sciences, DST, Ministry of Human Research Development, Govt. of West Bengal, GSA etc. I have developed the first regional groundwater flow model of the western Bengal basin and explored arsenic-safe aquifers in extensive parts of the Gangetic plains and delta. The findings have influenced the groundwater usage policy by Government of India. I received the first Shanti Swarup Bhatnagar Award 2020 in groundwater and selected by DST as one of 50 Indian scientists below 50 years age
