Rohan Choudhury

I’m a PhD student in the Robotics Institute at Carnegie Mellon University, advised by Kris Kitani and László Jeni. I’m supported by the NSF GRFP Fellowship, and have spent time during my PhD at Meta FAIR. working with Jing Huang.

I’m broadly interested in making video understanding faster and more efficient. In particular, I work on enabling vision algorithms to continuously perceive the world in high resolution and at 30+ FPS.

Before starting my PhD, I was a software engineer at Nuro, where I worked on trajectory forecasting models for self-driving vehicles. Even before that, I graduated from Caltech with a B.S. in Computer Science, where I worked on multi-agent reinforcement learning with Yisong Yue.

Outside of research, I enjoy running, lifting weights, watching sports and listening to electronic music.
