I am a geochemist interested in understanding low-temperature Earth surface geochemical processes. Understanding these processes can help us better constrain the past evolution of climate, hydrology, and vegetation and their interactions. I frequently rely on the chemical and isotopic signatures of marine and terrestrial sediments and river water samples to understand some of these processes.

Currently, I am working as a postdoctoral researcher at the IBS Center for Climate Physics (ICCP). Here, my research primarily focuses on understanding local hydrological dynamics, mainly the infiltration process at the karst system and long-term atmospheric circulation, utilizing 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 objectives, 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.

My PhD research focused on the impact of climate on land surface processes at different time scales, ranging from seasonal to kilo-year. Therefore, I am very keen on understanding climate-erosion linkage, paleoceanographic processes, and depositional environment (redox state) using sediment geochemistry. (read more)
