My research mainly focuses on understanding and quantifying low-temperature aquatic geochemical processes, which includes chemical weathering patterns of river basins from India, Re-Os geochronology of ancient marine organic-rich sediments, and tracing sediment provenances of marine sediments in kiloyear timescales. Towards this, I frequently rely on abundance and distribution of radiogenic isotopes ( ⁸⁷Sr/⁸⁶Sr, ¹⁸⁷Os/¹⁸⁸Os and ε_Nd) and trace elements of geological samples. My current research project aims at assessing role of ion-exchange processes and submarine groundwater discharge in regulating trace elemental inventory of coastal lagoon (Chilika lagoon, India) and large river systems from the tropical region.
