π About
I am a senior student at Beijing University of Posts and Telecommunications, majoring in Internet of Things Engineering. Before that, I studied at Shenzhen Middle School. I am currently seeking research collaborations and MPhil/PhD opportunities. Feel free to contact me!
My research interests lie primarily in AI Security & Safety and Robotics. On the security & safety side, I currently focus on Agent Security & Safety, particularly external attacks aimed at extracting sensitive information and risks arising during instruction following and action execution, as well as defense mechanisms against such threats. My long-term goal is to build efficient agents that preserve sensitive information and operate within explicitly granted permissions. On the robotics side, I am interested in Agents for Embodied Intelligence, and I hope to bring these directions together to develop secure and trustworthy embodied systems.
Outside of research, I enjoy playing basketball as a SG/PG. I am a fan of Kevin Durant and Anthony Edwards. Looking forward to seeing the Minnesota Timberwolves πΊ and the Houston Rockets π to meet in the Western Conference Finals this year!
