Research Interests

1. CO2 evolution in the paleo-atmosphere; probing the soil carbonate archives.
2. Reconstruction of paleo-diet using stable isotopes method.
3. Understanding the extinction event in geological time.
4. Carbon cycle in hydrosphere-atmosphere (Ocean, estuary, lakes etc.)
5. Stable isotope chemistry of atmospheric CO2 and carbon cycle.
6. Application of doubly substituted CO2 isotopologues in carbonate Paleo-thermometry.
7. Development of new isotopic standard for analyses of stable isotopes in air and solid samples.
