About

I am a first-year Ph.D. student in People, AI and Robotics (PAIR) group at University of Toronto, supervised by Prof. Animesh Garg and Prof. Andrea Tagliasacchi. Before that, I received my Bachelor's degree from the Department of Automation, Tsinghua University, where I was fortunate to work Prof. Jiwen Lu. I spent an unforgettable summer in 2020 doing internship at Stanford University, advised by Prof. Leonidas J. Guibas.

My research interests are in computer vision and robotics, particularly 3D scene understanding and their applications to robotics. I am broadly interested in designing machine learning systems that can perceive the world as we human do, which I believe is the cornerstone of achieving AGI.

Miscellaneous

I like swimming and I am particularly good at freestyle. I also like basketball. My favorite player is LeBron James.

I am also an Anime fan and a lover of Visual Novel. Some of my favorite works are Fate/Stay Night, Hyouka, Steins;Gate, EVA and Subarashiki Hibi (a.k.a. Wonderful Everyday).

Two persons I admire the most: Kaiming He for his outstanding research tastes and Elon Musk for his aspiration and enthusiasm.

I write an article summarizing the experience during my CS PhD application process. Take a look here (written in Chinese)!
