Professor and Head of the Department
Subjects of my research interest are physics and techniques of remote sensing. I have full-time teaching experience at honours (since 1996) and postgraduate (since 2002) levels with active involvement in laboratory and curriculum development. I have executed administrative jobs of head examiner and paper setter and written text books and popular science articles.
B. Sc. Physics (C. U. 1987)
M. Sc. Electronic Science with gold medal (C. U. 1989)
Ph. D. Electronic Science (C. U. 1997)
I spent school life in Bihar, then completed graduation and post-graduation and obtained doctoral degree under the University of Calcutta. I was the recipient of National scholarship and CSIR-UGC research fellowship on the basis of NET. I started professional career as lecturer in government college under West Bengal Educational Service. The same was continued until joining Presidency University in October 2012. At present I am Associate Professor in Physics at Presidency University. Along with regular undergraduate and postgraduate teaching and academic & administrative workload, I am actively engaged with researches and have conducted several research projects funded by the Government of India. A research scholar has been awarded Ph. D. degree from the University of Calcutta under my supervision. I have delivered invited talk at international symposium and acted as resource person in teachers’ training course and UGC sponsored refresher course.
Research / Administrative Experience+
Remote sensing, my favourite subject of research is the science and technology of detecting the electromagnetic radiation emitted, absorbed, transmitted and reflected by earth surface and atmosphere from far distance, such as aircraft and artificial satellite and acquiring information on natural resources, environment and human activity. It is a wide field of work incorporating multifarious and interactive researches of conventional and interdisciplinary subject areas like physics, atmospheric science, geography, geology, life sciences, electronics, computer science and many others. Main topics of my research are the physics and methodology of remote sensing including standardization of spectral signatures of terrestrial objects and identification of their origin with laboratory spectroscopy and satellite image analysis. I have conducted several research projects as PI funded by DST-NRDMS, CSIR and UGC, published research papers in reputed journals and acted as Referee in internationally reputed journals like IEEE Transactions on Geoscience and Remote Sensing, IEEE Photonics Technology Letters and International Journal of Remote Sensing. The Remote Sensing Laboratory of the Department of Physics, Presidency University was established during 2005-06 mainly with the project grants sanctioned to me. The existing research facilities comprise spectroscopic studies in ultraviolet-visible-infrared wavelength range and satellite image analysis. A good collection of books and study materials are available. Some remarkable achievements obtained with this laboratory are: • Ph. D. degree of a research scholar, • an elective paper of 50 marks on Physics of Remote Sensing for M. Sc. Physics students, being continued for the last five years, • research collaboration with other departments of this institution and other institutions and • several project works carried out with students of this department and others.
Teaching / Other Experience+
I have been in full time teaching profession at West Bengal Government colleges for more than 16 years, out of which almost 11 years have been spent in Presidency University (formerly Presidency College) with engagement of both UG and PG classes covering a wide range of levels including B.Sc. Pass/ED, Honours/Major, M.Sc. General and Special/Advanced papers of both theoretical and practical classes. Each one has its own importance and no one is less significant. Depending on the nature of the class, different strategies are followed in delivering lectures. Some of the students grow interest in higher studies and join research institutes for pursuing research work. Looking towards them, I suggest interpreting the scope for further studies and future prospects of the topics allotted. Discussion on model questions for competitive examinations and conducting project work are encouraged. A significant number of students go to teaching professions in schools and colleges. Thinking of such students, I raise in the class some topics on background knowledge and history of science.
Post Graduate Supervision+
A research scholar has achieved Ph. D. Degree (2010) of the University of Calcutta under my supervision.
