I am a third-year PhD candidate in the School of Computing at the National University of Singapore. I study streaming perception for embodied and interactive agents in a 4D world. I am a part of CVML@NUS advised by Angela Yao. My graduate research is supported by the President's Graduate Fellowship.

In the summer of 2024, I interned at Meta Reality Labs, hosted by Fadime Sener. Previously, I completed my bachelor's in ECE from Jadavpur University where I worked with Sanjoy Kumar Saha and Ananda S. Chowdhury.
