Presidency University

I am a specialist in igneous petrology, geochemistry, mineralogy. I use to teach these subjects both in undergraduate and post graduate level. My research interest is focused on petrological, geochemical and mineralogical studies of mafic magmatic rocks of Deccan Traps of western India and mafic magmatic rocks of eastern Indian shield (Singhbhum and Chottanagpur Gneissic Complex). I am trying to understand the evolution of magmatic rocks of Large Igneous Province and role of mantle plume in such evolution. Also I have been working on petrological and geochemical characterization of magmatic rocks of different tectonic setting. From the study of magmatic rocks I am trying to decipher the composition of mantle source rock, the melt generation process, role of volatiles in magma generation, crystallization process in magma chamber, magma transport and the mechanism of emplacement of these magmatic rocks.I am also trying to verify the existing models of magmatic evolution with the help of data collected from field and laboratory. I always prefer to teach students giving them a blend of research. Recently I have been working on the REE mineralization in carbonatite-alkaline rock association and magmatic magnetite deposits of Chotanagpur Granite Gneiss Complex (CGGC).

B.Sc. (3 year Honours in Geology)- 1983-Calcutta University

M.Sc. (2 year Course) - 1985-Calcutta University

Ph.D.(Sc) on Igneous Petrology, geochemistry- 1996-Calcutta University

My doctoral work started in January, 1987 in the Department of Geology, Presidency College, Kolkata. I worked for a period of two and half year as full time scholar and in July 1989 I joined West Bengal Education Service as Lecturer in Geology, Durgapur Govt. College, I continue my research work as part time scholar and submitted Ph.D. thesis in 1994. I was awraded Ph.D. (Sc) degree in 1996 from the Calcutta University. I worked on the evolution of Proterozoic bi-modal basalt-rhyolite association and associated granitoid rocks of one of the central Indian basin-Dongargarh Basin. After my Ph.D. degree I started carrying out research work in different Major research Project sponsored by DST, UGC. In 1998 I was tranferred to the Presidency College and joined there as Reader in Geology. I supervised about 50 M.Sc dissertation work. One student was awrded Ph.D.(Sc) gegree under my supervision in 2011 from Calcutta UNiversity. Now I have two Ph.D. scholars and two Post Doctoral fellows working under my supervision and mentorship. I am now associated with three ongoing major Projects as Co-Investigator and Mentor. I have one Major Project from DST(GoI) recently.

a) Started Ph.D. related research work as UGC Fellow in January, 1987 and continued up to July, 1989 as JRF in the Department of Geogy, Presidency College, Kolkata under the Supervision of Prof.P.K.gangopadhyay. Then after joining Durgapur Govt. College as lecturer continued research work as part time Ph.D.Fellow. Submitted Ph.D thesis on 1994 in the University of Calcutta and awarded Ph.D (Sc) degree on 1996. Thesis title: Structure and stratigraphy of the Precambrian rocks 0f Amgaon-Deori region, M.P. and Maharastra, Central India with special referencve to Petrology of selected igneous suite.

b) After 1996, research work has been continuing taking financial assistance from different Research Projects of UGC, CSIR, DST, DST-NSF Indo-US collaborative research, SAP-UGC (Details of Research Projects given in separate sheet as Annexure I).

My teaching experience spans over a period of34 years. During the entire period I teach both undergraduate and post graduate students, both theory and practical. I taught subjects like crystallography, mineralogy, igneous petrology, geochemistry, mathematic geology and Archean stratigraphy. I started teaching in 1989 as Lecturer in Geology in Durgapur Govt. College and continue there upto 1998. From 1998 till date I have been teaching in Prsidency College (later Presidency University). I am fortunate that I have enjoyed teaching both undergraduate and post graduate students throughout my entire teaching period which help me to continue my research.
