About the Faculty
Prof. Anjan Chattopadhyay joined BITS-Pilani, K.K.Birla Goa Campus, Department of Chemistry, in July 2005. He mainly teaches Quantum Mechanics, Group Theory and Physical Chemistry courses. His area of research expertise is in theoretical & computational chemistry which includes quantum mechanical calculations on organic and bio-inorganic systems. His major area of research interest (See his Research Page) lies in computational studies of photochemical and photophysical processes. His field of research work also includes quantum mechanical studies on van der Waals molecules. Funding agencies for his research work include Department of Science and Technology (DST), Council of Scientific and Industrial Research (CSIR) and Board of Research in Nuclear Sciences (BRNS). As a reviewer, he has reviewed papers for several reputed national & international journals. As a visiting researcher, he was associated with the Theoretical Chemistry Group of Prof. Dr. Horst Köppel, Institute of Physical Chemistry, University of Heidelberg, Germany, and has ongoing collaborative research work with his group on the photo-isomerization of linear polyenes. His collaborative work with the experimental groups include computational studies on the photophysical properties of organic molecules. These include studies on AIE properties, energy transfer processes, quenching through TICT states, ESIPT, ESPT and so on.
He received his Bachelor’s (1996) and Master’s degrees (1998) from Calcutta University. He was ranked first in Physical Chemistry and second in Chemistry from Calcutta University, and received Prof. Sadhan Basu Memorial award. He was also the recipient of Cunningham Memorial award, Sir Upendra Nath Bramachary Memorial award and Sandip Shome Memorial award from Presidency College, Kolkata.
