About
I’m currently an undergraduate student at Hangzhou Dianzi University and ITMO University, having enrolled in Fall 2023, and I’m pursuing a Bachelor’s degree in Computer Science and Technology.
From May 2026, I work as a Research Intern (青云人才计划) at Hunyuan Group, Tencent.
I am seeking PhD positions for 2027 Fall and warmly welcome any research internship. Please feel free to contact me!
I study agents.
