Short bio: I am an assistant professor and Zhu Chair at UCSB CS.
I completed my Postdoc at UC Berkeley as part of the RDI center and BAIR Lab, under the mentorship of Prof.
Dawn Song.
I received my Ph.D. from Penn State with Prof. Xinyu Xing and my master's
degree from Shanghai Jiao Tong University.
Outside of research, I am also leading the Agent Security R&D at Virtue AI, as well as serving a Faculty advisor at Google DeepMind.
Research Interests
My current research centers around:
LLM agents and agentic RLs for software engineering and security
LLM reasoning and post-training for coding
AI agents security and safety
My previous works studied the trustworthiness of DRL and DNN via statistical modeling (e.g., Deep GP, Gaussian process
models) and learning (e.g., variational inference, MCMC, empirical bayes),
and designing DNNs for security applications with a focus on noisy learning and OOD.

Student hiring Fall'26
I am actively recruiting Ph.D. students. If you have a solid background in LLMs, DRL, or software analysis skills
(static analysis, fuzzing, symbolic execution) and are interested in working with me, please do not hesitate
to contact me through email. [Ad in Chinese for Fall'26]
