About

I am a Royal Society – Newton International Fellow in the Department of Geography and Earth Sciences at Aberystwyth University, where my research focuses on characterising surface water dynamics in global drylands — asking how wetlands will respond to future environmental change, and what role they can play as sentinel indicators of climate shifts.

My work sits at the intersection of computational geoscience, fluvial geomorphology, and hydrology, combining multi-temporal Earth observation datasets (optical, radar/SAR, InSAR) with field campaigns across India, Spain, USA, and Argentina. A recurring theme is the concept of geomorphic connectivity — understanding how landscape components are linked across space and time.

Before Aberystwyth, I held an Alexander von Humboldt Postdoctoral Fellowship at the University of Potsdam (Germany), working on floodplain hydrogeomorphic dynamics using radar interferometry, and Postdoctoral and Project Scientist positions at IIT Kanpur (India), leading ISRO- and WWF-funded projects on wetland mapping, floodplain connectivity, and restoration.

I completed my PhD at IIT Kanpur in 2019, studying the geomorphic evolution, connectivity, and dynamics of Kaabar Tal — a large tropical floodplain wetland in North Bihar, India, which was subsequently designated a Ramsar site. I am currently mentored at Aberystwyth University by Prof Stephen Tooth.
