I’m a third-year Computer Science Ph.D. student in the CILVR lab at NYU Courant, advised by Mengye Ren and collaborating with Greg Durrett and Seunghoon Hong. My research is supported by the NSERC PGS-D Scholarship. Prior to joining NYU, I received my bachelor’s degree in Computer Science and Mathematics from the University of Waterloo.

I’m currently interested in:

  • LLM Reasoning and Test-Time Scaling: understanding and improving how LLMs adapt, reason, and self-improve at inference time.
  • World Models and Embodied Reasoning: learning world models from video and interaction data and leveraging them as simulators, planners, and co-training objectives.

Previously, I did research and software engineering for autonomous driving and ML for health at NVIDIA, Waabi/Uber-ATG, IBM, and DarwinAI. I was fortunate to have worked with Raquel Urtasun, Sanja Fidler, and Alexander Wong.

I’m happy to discuss collaboration, mentorship, and research in general. You can email me for a virtual or in-person chat. My office is at 60 5th Ave, New York.
