About Me

I am a Physical AI researcher at Huawei Noah's Ark Lab, Montreal. Before joining Huawei, I worked on computer graphics and obtained my Master and Ph.D of Computer Science at Concordia University in 2022 and 2026 respectively, supervised by Dr. Tiberiu Popa. I received my Bachelor's degree in Electrical Engineering at Beijing Jiaotong University in 2020.

In life, I am a lover of animals. We raise a cute dog Rice Cake and a handsome cat Wangwang.
