Since industrial revolution ever increasing human activities are constantly modifying the natural metal cycles which are directly impacting our food, water quality and climate. My research includes studying natural biogeochemical cycles of toxic metals in the environment and the perturbation of the natural cycles by anthropogenic processes. Along with concentration study, I combine the isotopic signature of elements to study the sources, pathways and sinks of the contaminants in preindustrial and contemporary environments. The concentration measurements are used to quantify the magnitude of anthropogenic perturbations, and the isotopic composition are useful for source fingerprinting. I primarily use the multi-collector inductively coupled plasma mass spectrometry (MC-ICPMS) to measure the stable isotopic fractionation of metals.

My main research interests are:
- Mercury biogeochemical cycle
- Arsenic biogeochemistry
- Radiometric dating techniques
- Radiogenic and stable isotope geochemistry
