About Me
Chang Yu

I am a Computer Science Ph.D. student at Artificial Intelligence & Visual Computing Lab, UCLA Department of Mathematics, co-advised by Prof. Chenfanfu Jiang and Prof. Demetri Terzopoulos. I graduated with honors from the University of Electronic Science and Technology of China (UESTC), and I was a Research & Development intern at Taichi Graphics, where I was fortunate enough to be supervised by Dr. Tiantian Liu.

My research interests lie in computer graphics, robotics, and computational physics.
