About Me

Hello 👋 Thanks for visiting my website.
I was previously a postdoctoral researcher at CNRS Paris, collaborating with Marc Baaden on virtual-reality–based interactive molecular visualization. I obtained my PhD from Inria at the University of Bordeaux under the supervision of Martin Hachet, following an MS (by Research) from IIT Kharagpur and a B.Tech from West Bengal University of Technology. My research focuses on Human–Computer Interaction, particularly the design, implementation, and evaluation of interaction techniques for immersive AR/VR systems.
