Hi, I'm Xiangyu Li (李翔宇)

I'm a fifth-year Ph.D. candidate at the Institute for AI Industry Research (AIR), Tsinghua University, advised by Prof. Yunxin Liu and working closely with Prof. Ting Cao. I received my B.E. in Electronic Engineering from Tsinghua University in 2022.

I work on on-device AI and embodied AI, with a current focus on efficient deployment of embodied foundation models (VLAs and WAMs) and self-evolving physical intelligence. Homepage · RedNote
