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

  My research interest focuses on reconstruction of seasonality through time using empirical relationships between the proxy records and climate parameters, and application of stable isotope technique to understand environmental processes. Most notable contributions have been the establishment of clumped isotope thermometry, generating standards for mass spectrometric analysis of solids and gaseous CO2 in air mixture, application of isotope based GCM to study Indian Monsoon precipitation.
  In addition, I am involved in monitoring environmental changes in coastal marine and adjoining agroecosystems. My recent works focus on investigating temporal and spatial variability of concentration and d13C of atmospheric CO2 over land and oceans, climate reconstruction during the late Holocene, development of high-resolution proxies for deriving rainfall at sub-annual timescales and using stable isotopes in rice grains as proxy for deducing past hydroclimate.
