Hsueh-Ti (Derek) Liu

I am a second-year Computer Science PhD student at the University of Toronto, advised by Alec Jacobson, and a member of Dynamic Graphics Project. My research focuses on 3D geometry processing using spectral, differentiable rendering, and machine learning approaches. I received my BSE at National Taiwan University, and MS at Carnegie Mellon University advised by Keenan Crane and Levent Burak Kara. Currently, I am doing my internship at Adobe Research, Seattle, mentored by Vova Kim. Previously, I was visiting Maks Ovsjanikov at Ecole Polytechnique.
