I am a structural biologist by both training and passion. I received my Ph.D. in Structural Biology (Protein X-ray Crystallography) in 2015 from the Indian Institute of Technology Kharagpur under the supervision of Prof. Amit Kumar Das (Department of Biotechnology). My doctoral research focused on understanding how the conformational dynamics of bi-domain enzymes are intertwined with their catalytic mechanisms.
I worked as a postdoctoral scientist at the University of Oxford (Radcliffe Department of Medicine), where I studied the role of transcriptional regulation during the early stages of hematopoietic development. Prior to that, I was a CNRS postdoctoral researcher at École Polytechnique in Paris, France (Laboratoire de Biologie Structurale de la Cellule), where I investigated the structure and function of protein complexes involved in eukaryotic ribosome biogenesis and RNA modification.

My current research area is structural biology and protein engineering. The team is working on,
- protein complexes involved in epitranscriptomic modification,
- discovering new targets for structure-based drug designing against cancer and fatal multi-drug resistant strains
- de novo drug designing
- scaffold-based vaccine designing
- studying conformational dynamics of protein and protein RNA complexes by molecular dynamics simulation and X-ray crystallography.
