Prosenjit Ghosh obtained his BSc (Geology) (1991) from Hansraj College, Delhi University and MTech in Applied Geology (1994) from University of Roorkee (Uttar Pradesh) and PhD (2000) from Physical Research Laboratory (PRL), Ahmedabad, while working under the supervision of S.K. Bhattacharya. Subsequently, he was Postdoctoral Fellow (2001-2002) at PRL.
  He was WMO-IAEA post doctoral fellow at Max Planck Institute for Biogeochemistry, Jena with Willi Brand and Caltech postdoctoral fellow with John Eiler. He worked as an Assistant Professor at Tokyo Institute of Technology, Tokyo, Japan during 2006-2007. He joined as an Assistant Professor in the Centre for Atmospheric and Oceanic Sciences, Indian Institute of Science in the year 2007 and became a core faculty at the Centre for Earth Sciences in the year 2008, soon after its creation. He is adjunct faculty in other departments which includes Centre for Atmospheric and Oceanic Sciences and Divecha Centre for Climate Change.

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.
