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.
