I am a geochemist, primarily interested in low-temperature geochemical processes to understand better the past evolution of climate/hydrology/vegetation and their interactions. Recently, I graduated from the Earth and Climate Science Department of the Indian Institute of Science Education and Research (IISER) Pune. My Ph.D. research focused on the impact of climate on land surface processes at different time scales, ranging from seasonal to kilo-year. I frequently use geochemical and isotopic signatures of marine and terrestrial sediments and river water samples to answer some of these questions.

Currently, I am working as a postdoctoral researcher at the IBS Center for Climate Physics (ICCP). Here, I am focusing on two major aspects: (i) local hydrological dynamics, mainly the infiltration process at the karst system, and (ii) long-term atmospheric circulation, that is the dust supply, using trace-elemental and isotopic compositions of speleothem samples collected from different parts of the world. I am also involved in a cave system monitoring program to understand how the karstic zone influences speleothem chemical compositions. To address my research objective, I established an analytical protocol of one laser ablation (193 nm ArF Excimer) system coupled with a mass spectrometer (LA-ICP-MS) at ICCP for analyzing speleothem trace elemental compositions.

I have a great interest in understanding climate-erosion linkage, as well as paleoceanographic processes and depositional environment (redox state) using sediment geochemistry. (read more)
