Yijia Weng | 翁伊嘉

I am a rising fifth-year Ph.D. student in computer science at Stanford University, advised by Prof. Leonidas Guibas. Previously, I obtained my B.S. in Computer Science from Turing Class, Peking University, advised by Prof. Baoquan Chen. I also had the privilege of working closely with Prof. Jeannette Bohg at Stanford, Prof. Hao Su at UCSD, and Prof. He Wang at Peking University. I've had a wonderful time pursuing research internships at Adobe Research, NVIDIA Research, and Google Deepmind.

Research

My research interests lie in 3D computer vision, with a focus on reconstructing the 3D world with efficient, interaction-aware, and semantically meaningful representations.

Miscellaneous

I was quite into competitive programming💻 and used to compete in Olympiad in Informatics and International Collegiate Programming Contest (ICPC)🏅. Now I also train high school students back at home. Solving those brain teasers is always fun!
In my spare time, I enjoy dancing💃, cooking🍳, concerts🎫, musicals🎭, and learning foreign languages🇫🇷🇰🇷.
