I belong to the clan of Structural Geologists who studies rock deformation and evolution of the orogenic/ mountain belts all over the globe with utmost enthusiasm. I got interested in the subject for the primary reason that it offered a key for unravelling the complex 3-D geometries and evolutionary processes of the mountain belts, the study of which provide vital clues regarding tectonic processes occurring on and within the earth such as earthquake activities, volcanic eruptions or plate movements. Besides, the orogenic belts also serves as the storehouse of vast resources of metallic and nonmetallic deposits, fossil fuels including petroleum and nuclear fuels, the careful exploration and utilization of which played pivotal roles behind the growth of human civilization to its present status.
BSc (Geology), Calcutta University, 1982
MSc (Geology), Calcutta University, 1984
PhD. (Science), Calcutta University, 1999
I did my doctoral thesis on unclassified Mesoproterozoic sequences of the Pranhita-Godavari valley bordering the Bastar and East Dharwar cratons of the southern Indian block from Calcutta University. I started working on the problem while I was enjoying a Junior Research Fellowship at Indian Statistical Institute, Kolkata and pursued the work after joining the West Bengal Educational Service and earned Ph. D. I joined Presidency University in 2013 after serving in two Government Colleges for nearly twenty four years.
Research / Administrative Experience+
At present, I am particularly interested in identification and quantification of crustal scale deformation processes associated with discrete tectonic events in fold-thrust belts from Precambrian terrains. I am also interested in microstructural evolution and grain-scale deformation processes in low-to-high grade metamorphic terrains.
My long-term research goals include:
(1) Field-based structural geology and tectonic evolution of Precambrian orogens in India.
(2) Integration of structural geology with palaeomagnetism to solve regional tectonic problems.
(3) Strain analysis and partitioning of strain data for understanding grain-scale deformation processes.
(4) Understanding structural control on mineralization with particular emphasis on iron and uranium.
(5) Tectonostratigraphic evolution of the Himalayan Frontal Fold-Thrust belt
I have successfully completed and pursuing several major research projects funded by DST, BRNS, CSIR and MOE as Principal Investigator and Co-Investigator.
Teaching / Other Experience+
I have been engaged in teaching for about last 25 years. I teach Structural Geology, Tectonics and Precambrian Stratigraphy at undergraduate and postgraduate levels. The Structural Geology courses include both theory and laboratory based classes.
I have supervised about 25 M.Sc. dissertations in different branches of Structural Geology as part of the regular postgraduate course. Till date, one Ph. D. scholar has submitted her thesis to Calcutta University and there are several others pursuing their Ph. D. programmes under my supervision.
