• Dr. Debasish Chattopadhyay received his BS in Chemistry and MS in Biochemistry from Calcutta University, India. He obtained Ph.D. degree in Chemistry from Jadavpur University, India in 1989. He conducted his postdoctoral research at the Upjohn Company in Michigan. This work was part of an NIH funded collaborative effort involving several academic institutions and pharmaceutical industries for the discovery of potent antiretroviral drugs. Dr. Chattopadhyay's work focussed on the structure-function analysis of target enzymes its application in drug development. Dr. Chattopadhyay joined the University of Alabama in 1994 and was recruited as an Assistant Professor in the School of Medicine in 1998. Dr. Chattopadhyay was promoted to the Associate Professor rank in 2007 and to the Professor rank in 2013.

    Research Overview

  • Structure-Function Analysis of Proteins - The main objective of our research is to define the relationship between the structure and function of biological macromolecules. Our research focuses on macromolecules that regulate the key steps in the life of eukaryotic and prokaryotic pathogens including parasites, bacteria and viruses. Results of our investigations inform drug discovery and vaccine development. We use a variety of biophysical and biochemical techniques in our studies.
