Research Interests


I try to understand the physical and chemical processes in the Earth by analyzing the chemistry of its rocks. In particular, I am interested in the application of geochemical (including isotopic) proxies for both high (mantle evolution) and low-temperature (surface processes) related studies. I also work to understand the petrogenesis of Deccan Traps and Rajmahal Traps basalts. Recently, me and my students are attempting to estimate the composition of the Indian Continetal crust.

My current research also includes reconstruction of Quaternary paleoclimate (and paleovegetation patterns) of India, with respect to the major shifts in southwest monsoon strength and precipitation, from multiple climate proxies archived in sediment records of Indus-Gangetic basin and other alluvium, and archaeological (short-lived herbivores) material. In particular, proxies such as stable oxygen and carbon isotopic composition of carbonate nodules, paleosols, sediment/soil organic matter, and clay minerals recovered from well-dated horizons are utilized to reconstruct climate history during the Quaternary.
