Presidency University

I am always intrigued by the might of the mountains and my passion drove me eventually to the study of orogenic belts. Orogenic belts with towering peaks similar to what we see in the modern day Himalayas also existed long back in the Earth’s history that are now lying as eroded mountain belts surrounding the cratonic blocks of India. I was trained so far in tracing the history from “microscope to mountain belts” using the tools of metamorphic petrology (texture, chemistry and more robust pseudosection analysis). A substantial exposure to geochronology opened my vision about the complexity of the crustal processes wherein the knowledge of so many important branches of earth science merges. I understood the necessity of scientific research in a holistic approach assembling key members from different earth science communities.

B.Sc. in Geological Sciences (Jadavpur University, India, 1991)

M.Sc. in Applied Geology (Jadavpur University, India, 1993)

Ph.D. in Science (Jadavpur University, India, 2003)

I did my doctoral rsearch on petrological evolution of the Eastern Ghats Belt of India and awarded the degree in 2003. In the year 2007, I moved to Yokohama National University, Japan with a two-year Post-Doctoral Fellowship from JSPS. I also invited to Hiroshima University, Japan for three weeks in 2012 and Yokohama National University, Japan in 2013. I joined Presidency University as an Associate Professor in 2013. I received National Geoscience Award (2012) by Govt. of India for outstanding contribution in the field of Basic Geoscience. In the year 2016, I was awarded the JSPS-Bridge Fellowship to work with scientists from Hiroshima University and Nagoya University, Japan. I became a member of the international research group Hiroshima Institute of Plate Convergenece Region Research (HiPeR) in 2017. I received the INSA Teachers Award in the year 2019. I also received Shiksha Ratna award from the Government of West Bengal in 2019.

My research interest is focused on evolution of lower crust from petrological study of high-grade metamorphic rocks of the Eastern Ghats Belt (EGB) of India. Characterization ultrahigh temperature (UHT) metamorphic process in this belt is an important contribution to the knowledge of crustal evolution. During my post-doctoral research program in Japan, I developed interest in geochronology and experimental petrology. The geochronological study was done with very high-resolution state-of-the-art technique (SHRIMP) and yielded significant results for the crustal evolution of the EGB and its role in the Proterozoic accretionary processes involving extinct supercontinents Columbia, Rodinia and Gondwana. My interests on structural geology, geochemistry and tectonics help me understand problems of Precambrian geology in a holistic manner. As Principal Investigator, I successfully completed seven major research project funded by DST, CSIR, MoES including two International Bilateral projects (DST-JSPS).

I teach Metamorphic Petrology in under-graduate and post-graduate courses. These contain both thery and laboratory-based coursework. I also teach Introduction to Earth System Science and Crystal Chemistry in under-graduate level and Geochemical Thermodynamics in post-graduate level.

Three doctoral students received Ph.D. degree- Arnab Dasgupta (2018), Proloy Ganguly (2019) and Sneha Mukherjee (2019). Currently three students, Aparupa Banerjee, Arnob Kumar Mondal and Shuvankar Karmakar are pursuing Ph.D. degree.
