Prof. Bhattacharyya completed his B. Sc. (Chemistry) in 1990 from Ramakrishna Mission Vivekananda Centenary Collage (University of Calcutta) and M. Sc. (Biochemistry) in 1992 from University of Calcutta. He performed his Ph. D. work (Molecular Biology: 1993-1998) at Tata Institute of Fundamental Research (Mumbai), where he investigated molecular aspects of naturally acquired immunity to human malarial parasite Plasmodium falciparum.
Prof. Bhattacharyya worked as a Post Doctoral Research Fellow at Johns Hopkins University, USA (1999-2004), where he initiated the study on homologous recombination (HR) in P. falciparum; and begin to understand how HR could be involved in the generation of genomic diversities in this parasite.
He started his career as a Research Scientist in Tulane University School of Medicine, USA (2004-2007), where he worked on DNA repair and telomere maintenance of yeast chromosomes and found intriguing relationship between Mre11 (a protein involved in DNA repair) mediated DNA damage response (DDR) and telomere maintenance. He also worked as a Visiting Research Scientist in Northwestern University, USA (October 2005-January 2006). He is a recipient of prestigious INDO-US Professorship in microbiology from the American Society for Microbiology (2009).
Dr. Bhattacharyya joined University of Hyderabad in March 2007 as a Reader of Biochemistry. Currently (since April 2015) he is a Professor of Biochemistry. He has served as the Head of the Department of Biochemistry from 1st February 2017 to 31st January 2020. His teaching activities include Molecular Biology; Gene Regulation and Recombinant DNA Technology. He has received the Chancellor’s Award in 2014 from the Chancellor of University of Hyderabad for his outstanding contributions to teaching and research. Prof. Bhattacharyya’s laboratory at the University of Hyderabad has made seminal contributions in the field of DNA double strand break repair in the apicomplexan parasites.

Our longtime research interest is to unravel how nuclear and chromosomal context influence the seeming inaccuracy in DNA repair that provide a pathogen with the necessary means to manipulate the “host-pathogen interaction”. Thus research activities in our laboratory mainly revolve around two interlinked questions: 1) What are the mechanisms of DNA repair in Plasmodium; and 2) How do they contribute to genetic diversities that result in antigenic variation, the most potent means of immune evasion. Our laboratory is currently working on four interrelated directions:
Project 1: Development of an in vivo method, which will allow us to uncover (as well as differentiate between) various competing DNA repair mechanisms, operational in the parasite. This project will also identify the factors associate with these repair pathways.
Project 2: Characterization of the roles of individual factors in homologous recombination (HR) pathway in the parasite; and appreciate their contributions in accumulation of genetic diversities.
Project 3: Unraveling the roles of HR in Plasmodium biology, particularly during the repair and replication of the organellar genomes.
Project 4: Study of functional biology of Plasmodium telomeres in order to get insights into how telomere dynamics regulates structure and functions of virulence genes.
Understanding such processes, in comparison to those involved in human, would not only have the potential for generating novel therapeutic interventions, but would also contribute to our fundamental knowledge of genetic and epigenetic control of eukaryotic DNA repair.
