About the Faculty

Prof. Anjan Chattopadhyay joined BITS-Pilani, K.K.Birla Goa Campus, Department of Chemistry, in July 2005. His area of research expertise is theoretical & computational chemistry. His major area of research interest lies in computational photochemistry of organic and bio-inorganic systems. He is actively involved in studies related to photochemical reactions through conical intersections. His field of research work also includes quantum mechanical studies on van der Waals molecules. Funding agencies for his research work include different sponsoring bodies, such as Department of Science and Technology (DST), Council of Scientific and Industrial Research (CSIR), 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 did collaborative research work.

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. His Ph.D (2004) degree is from Jadavpur University, Kolkata.
