My key research mainly focuses on the geochemistry and thermodynamics of low-enthalpy hydrothermal systems. I use major and trace element geochemistry, chemical speciation, stable and radiogenic isotopes in groundwater to study the provenance and geothermal potential of hydrothermal systems in India. In addition, I am interested in research employing tracers in water to provide quantitative constraints on sources and processes in hydrology through temporal variation, forward and inverse modelling, and laboratory-based analytical experiments.
