Zihan Yu

I am a final-year Ph.D. candidate in the School of Information and Computer Science at the University of California, Irvine, advised by Shuang Zhao. Prior to UCI, I obtained an M.S. in Computer Science from Columbia University and a B.Eng. in Software Engineering from Tongji University.

I’m on the job market now–feel free to reach out if you’re interested!

Research: My research focuses on physics-based differentiable rendering and simulations using Monte Carlo method, with the goal of developing efficient solutions for inverse problems involving complex geometries to infer material or geometric properties from physical or simulated measurements.
