Area of Interest:
Sedimentology, Sequence stratigraphy, Stable isotope geochemistry

Research Interest:

My research focuses in studying the sedimentology, sequence stratigraphy, and stable isotope geochemistry of Palaeogene foreland sediments of Himalaya to understand the Tectonic-Climate Interaction which is believe to responsible for the Cenozoic Greenhouse-Icehouse Transition. While Sedimentologic and Sequence Stratigraphic analysis helps to identify the tectonic forcing on depositional patterns, stable isotopic analysis on various kinds of samples (organic matter, carbonate, water, clay, and bio-apatite) used to reconstruct the climate change during the deposition of these sediments.
