About Me

I am a Senior Researcher at Tencent America. Before joining Tencent America, I worked as a Software Engineer at Adobe for three years. I earned my Ph.D. from the University of North Carolina at Chapel Hill in 2020, under the supervision of Professor Ming C. Lin. I worked with Dr. Byungmoon Kim and Dr. Qingnan Zhou at Adobe as an intern. Before joining UNC, I was a research staff in UEI Research, where I worked with Professor Tomoyuki Nishita and Professor Yoshinori Dobashi. I received my B.S. and M.S. in Computer Science in 2012 and 2014, respectively, from Keio University, working with Professor Issei Fujishiro.

My research interests include physically-based simulation, numerical optimization, differentiable physics, geometry processing, deep learning, and artificial intelligence.
