Welcome

I am a researcher with nearly 12 years of experience in academic research. Currently, I serve as an Assistant Professor in the Department of Geology at Mizoram Central University in Aizawl. I earned my Ph.D. from the Indian Institute of Technology (Indian School of Mines) Dhanbad, Jharkhand, India, in 2021. I also completed my M.Sc. (First Class) in Applied Geology from the Department of Geology at Presidency University, Kolkata, West Bengal, India, and my B.Sc. (First Class with Honors) from the Department of Geology, Presidency College, University of Calcutta, West Bengal, India.

My research interests include organic geochemistry, organic petrology, stable isotope geochemistry, the geochemistry of coal bed gas and shale gas, paleoclimatology, and geoarchaeology. I am particularly focused on exploring interdisciplinary areas related to coal, shale, and petroleum geochemistry to enhance their applications for a cleaner future.

Qualifications: Ph.D. (Applied Geology and Applied Geochemistry; 2016-2021); M.Sc. (Applied Geology; 2013-2015); B.Sc. (Honors in Geology; 2010-2013)

research themes

Research themes:

Santanu conducts research works on organic petrology that includes maceral-micolithotype identification and quantification, vitrinite reflectance measurement and determination of optical anisotropy of coal and shale. The organic geochemical studies involve the investigation of heteroatomic chemistry of coal and shale of different rank using the X-ray Photoelectron spectroscopy, microstructural ordering through the Raman and Fourier Transform Infrared spectroscopy, stable carbon and nitrogen isotopic insights of bulk organic matter as well as lipid biomarker distribution in coals. Also, he takes keen interest in rare earth and trace element disposition in coal and shale along with major elemental oxide distribution to interpret the palaeodepositional environment and palaeoclimatic conditions. His interest also lies in palaeoclimatology using the lipid biomarker and stable isotopes as the tools. In complementary, he deals in stable isotopes of coal bed and shale gas and associated formation water to have a view on microbially enhanced methane production from existing and depleted wells.
