  • Contact: 04023134587
  • Area Of Research:Yeast genetics, Molecular and cellular Biology, Molecular Parasitology

Dr. Bhattacharyya completed her B. Sc. degree in 1991 with Chemistry Hons. from the Scottish Church College, University of Calcutta and M. Sc. in Biochemistry from the University of Calcutta in 1993. She obtained her PhD degree from the Department of Biophysics, Bose Institute, Kolkata in 2001, where she worked on the solution structure of lambda repressor.

In 2001, she joined Professor Flyod Randy Bryant's laboratory at the Department of Biochemistry and Molecular Biology, Johns Hopkins University as a postdoctoral fellow, where she worked on the biochemistry of bacterial RecA protein. In 2004, she moved to Tulane University and joined Professor Charles Miller's laboratory as a postdoctoral fellow. In that period (2004-2007) she worked on role of Hsp90 in steroid hormone receptor signalling.

In 2007, she came back to India and participated in the teaching program of University of Hyderabad, School of Life Sciences as a guest faculty. Followed by which, in 2009, she joined the Department of Biotechnology and Bioinformatics as an Assistant Professor. Currently, she is an associate professor. She teaches Molecular Biology and Genetic Engineering to the MSc. and integrated MSc-PhD students of the department.

Dr. Sunanda Bhattacharyya's laboratory works on the roles of Hsp90 and its cochaperones on genome stability. Another focus of her research is understanding the mechanism of DNA replication in human malaria parasite Plasmodium falciparum.
