Xi Deng
I am a postdoctoral researcher at Caltech, working with Prof. Anima Anandkumar. I received my Ph.D. in Computer Science from Cornell University, where I was advised by Prof. Steve Marschner in the Graphics and Vision Group. My research focuses on physically based light transport simulation, differentiable rendering, inverse problems, Monte Carlo methods, and neural operators for scientific computing.
Before joining Cornell, I was a master's student in the Digital Arts program at Dartmouth College. I completed my master's thesis in the Visual Computing Lab under the supervision of Prof. Wojciech Jarosz.
