I look upon teaching as a process to make the students think independently. Teaching is an interactive process which takes both the teacher and the learner towards an advanced learning.  Actually I am from Geography background. Quite naturally I put emphasis on learning as an holistic and integrated process incorporating physical landscape and cultural milieu. I think environmental happening can best be understood in a synthetic manner i.e. the integration of physical and social space. My field of specialization is Applied Geomorphology. Hence I often take the classes of geomorphology at UG and PG level. Besides taking classes of geomorphology I teach hydrology, climatology too. I think teaching geomorphology or landforms study may provide useful insights to the students for sustainable management of the environment and disaster management. As the environment is itself a holistic concept, it can be better understood if geomorphic understanding accompanies the students. I teach geomorphology not merely as a field of science rather to foster integration between geomorphic processes, society and economy to address disaster management as the geomorphic hazards like flood, river bank erosion are common in any river based civilization. My ultimate motto of teaching is to develop the students with their interdisciplinary outlook to sustain and revive our old civilizations.

Research Area

My research area is in the discipline of fluvial geomorphology. River bank erosion and its management in the Ganges delta is the prime focus of interest. I did my M.Phil dissertation on ‘Bank Erosion of the River Bhagirathi and Its Impacts on Agriculture and Economy- A Study in the Selected Areas of Nadia District, West Bengal. The area of enquiry at M.Phil level was further extended on the title ‘River Bank Erosion and Its Impact on Economy and Society: A Study along the Left Bank of River Bhagirathi in Nadia District, West Bengal at PhD level.’’

 My current research works include a. meandering behaviour of Bhagirathi and Jalangi; b. channel asymmetry analysis; c. river bank erosion mechanism with special reference to Bhagirathi by hydraulic control and fluctuating climate regime; d. integrating river bank erosion with vulnerability of society and economy; modelling mitigation measures for disaster management.
