Undergraduate from Hansraj College (BSc, Geology) Delhi University in the year 1991, Prosenjit continued his higher education completing his Masters in Applied Geology from University of Roorkee (now IIT, Roorkee). He developed his interests in geochemistry while conducting a study as a part of his dissertation on the genesis of mafic enclaves in Kolar greenstone granite. Later, he pursued his interests further after being selected as a scholar in the Physical Research Laboratory, Ahmedabad in the year 1994. While at PRL, he had exposures to mass spectrometry and advanced tool of geochemistry. His PhD work aimed towards understanding the paleo climate record of Gondwana sediments from different sedimentary basins in India. He contributed in the paleo-barometry research adding new estimates of past CO2 concentration in global atmosphere. Soon after, he had a brief tenure as Head Geochemist at Anglo American Exploration. He continued his journey exploring the tool of mass spectrometry and high precision analysis of carbonate after joining Max Planck Institute for Biogeochemistry, Jena, Germany in the year 2001 as IAEA- WMO postdoctoral fellowship. His contribution on developing a new Air CO2 mixture from carbonate received global attention and accepted as new standard reference material for isotopic analysis. He had a break though in his research credential after joining his next tenure as postdoctoral fellow at California Institute of Technology at Pasadena, USA in the later half of the year 2003. His research on carbonate clumped isotope thermometry received global attention and adjudged as a noble tool for past temperature reconstruction. In the year 2006, he got appointed as Assistant Professor, Tokyo Institute Technology and was instrumental in setting up the clumped isotope laboratory. Prosenjit joined IISc in the year 2007 as a Assistant Professor in the Centre for Atmospheric and Oceanic Science. Once IISc started a new Centre for Earth Sciences in the year 2008, he moved to the new Centre as a core faculty. He is presently affiliated with other centres in the campus engaged in multi-disciplinary application of stable isotope geochemistry. His research interests expanded in the academic ambience of IISc to include isotope hydrology, carbon sequestration, global circulation model, reconstruction of seasonality, exploring quaternary record using high resolution archives like gastropods, mollusc, rice grains and speleothems. During the course of his research carrier he had opportunity to work with several experts in the field which includes, Naohiro Yoshida, John Eiler, Willi Brand, S.K.Bhattachrya and S. Balakrishnan.
