I'm a 2nd-year PhD student in the Robotics Institute at Carnegie Mellon University. I'm co-advised by Deva Ramanan and Srinivasa Narasimhan. I also frequently collaborate with Shubham Tulsiani.

Previously, I received my BS in Computer Science from University of Minnesota, working with Stergios Roumeliotis and Hyun Soo Park. I also spent a summer at Enfusion Systems as a SWE intern during my undergrad.

I'm interested in computer vision, robotics, and machine learning, especially 3D/4D reconstruction and visual scene understanding.
