I am currently a first year PhD student at Université de Montréal (UdeM), advised by Dr. Mikhail Bessmeltsev. I am interested in Physics-based simulation and Character Animation in computer graphics.

In the past, I worked as a junior research assistant at Universal Machine Inc. and as an adjunct lecturer at the Department of Computer Science and Engineering, BUET.
