I spent my school life in Bihar and started schooling at Gouranga Pathshala, Jamalpur. Subsequent institutions were Railway High School and Sahibganj College. In those days, ISc used to be taught in colleges. I completed graduation from Gurudas College under the University of Calcutta and obtained MSc and PhD degrees from Science College, Rajabazar, University of Calcutta. I was recipient of National scholarship on the basis of BSc result 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 first posting was at the College of Textile Technology, Berhampore. Then I was transferred to Presidency College. During my service, the institution got upgraded to University status and I applied for the interview to join there.

At present I am Professor in Physics (w.e.f. 1st Oct. 2012) at Presidency University. Along with regular academic & administrative workload, I am actively engaged with research and have conducted several research projects funded by the Government of India, delivered invited talk at international symposium and acted as resource person in teachers’ training courses and UGC sponsored refresher courses.

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 conventional and interdisciplinary subject areas.

I have initiated researches on the physics and methodology of remote sensing in my department almost two decades ago, conducted several Govt. funded research projects and have been able to publish several research papers in reputed journals with single/prime authorship. Utilizing the project funds, I established a research laboratory where a PhD and a post-doctoral work have been completed. 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.

My present interest is on the remote sensing of atmospheric parameters, such as greenhouse gases and the related climate changes. I have got the opportunity to collaborate with Space Applications Centre, Indian Space Research Organization and by virtue of the collaboration have got access to their valuable remote sensing database procured by airborne sensor AVIRIS-NG flown for the first time in India.

The major portion, more than two decades of my teaching life has been spent in Presidency University (formerly Presidency College) with engagement of BSc and MSc classes covering a wide range of levels including Honours/Equivalent and Special/Advanced of both theoretical and practical papers. I believe, each one has its own importance and no one is less significant. Depending on the nature of the class, different pedagogical strategies are followed. Some of the students grow interest in higher studies and join research institutes for pursuing research work. Looking towards them, I interpret 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 classes the topics of basic concept, background knowledge and history of science.
