Professor

B. Sc. (Geology Hons.), Jadavpur University, Kolkata, 1990

M. Sc. (Applied Geology), Jadavpur University, Kolkata, 1992

Ph. D. (Geology) Jadavpur University, Kolkata, 2003

Hailed from a modest Bengali ambience of a suburb of Kolkata. Got B. Sc. and M. Sc. degrees from Jadavpur University (JU), Kolkata. Thereafter, pursued research work at JU; continued part time after getting a job at the Geological Survey of India, Kolkata and earned Ph. D. Had been engaged in teaching in West Bengal Educational Services for over fourteen years and served in two colleges before joining this university.

My research involves study of systematics and evolutionary palaeobiology of fossil marine molluscs.

I intend to make comprehensive interdisciplinary studies on some important fossil bearing sedimentary successions of India to unravel their depositional history.

Worked in different administrative committees in different capacities. Currently, I am the chairman of Equal Opportunity Cell of the University.

For the last about twenty five years I have been engaged in imparting state-of-the-art knowledge on “Invertebrate Palaeontology” and “Principles of Palaeontology” to undergraduate and post-graduate students. I have also dealt occasionally with courses on “Vertebrate Palaeontology”, “Micropalaeontology”, “Palaeobotany”, “Phanerozoic Stratigraphy of India” and “Principles of Stratigraphy”. As a part of the regular PG course I have supervised numerous M. Sc. dissertations. Two research students have completed their Ph. D. study under my supervision. Two students will submit their Ph. D. thesis soon. I mentored a National Post-Doctoral Fellow (NPDF).

I have imparted training on basics of Palaeontology to students from 10+2 level as part of their course for Earth Science Olympiad.

I have delivered talks on important evolutionary aspects, such as, mass-extinction to students from different levels and people from other walks of life. 

As part of the regular PG course I have supervised more than 30 M. Sc. dissertations.

Ph. D. supervision: (1) Two students have been awarded - (i) Dr. Shrestha Das (University of Calcutta); Title - Systematics, Palaeobiogeography and Palaeoecology of the Eocene Gastropoda (Mollusca) from Kutch, Gujarat. (ii) Dr. Aniket Mitra (Presidency university); Title -
