# Who I Am

Hi! I'm Yurun Chen, a Ph.D. student at Zhejiang University, advised by Shengyu Zhang and Keting Yin.

I work on the safety of Computer-Using Agents (CUAs). My research centers on two complementary questions: how to equip CUAs with effective guardrails for robust task execution under real-world noise and uncertainty, and how to systematically develop red-teaming strategies that uncover safety vulnerabilities in realistic deployment settings.

Open to collaborations on CUA red-teaming, safety, guardrails, and evaluation. Reach out via email.
