Broader AI research
Expanding at BIMSA into broader AI questions about reasoning, human-AI interaction, useful AI systems, and AI-assisted education through ongoing collaboration.
I welcome motivated students at all levels — undergraduate, master's, and Ph.D. — as well as postdoctoral researchers interested in broad AI research, trustworthy AI, AI-assisted systems, and AI security.
I also co-supervise student research, including collaborations with Huazhong University of Science and Technology since 2018 and Shanghai Jiao Tong University since 2025. Four Ph.D. students I co-supervised have graduated; three became assistant professors at Chinese universities, including one at Shanghai Jiao Tong University, and one joined a major Chinese technology company as a researcher.
Selected Highlights
Recent and representative work
Trustworthy AI and AI security
I continue to study LLM and agent safety, prompt injection and jailbreak robustness, model tamper detection and IP protection, adversarial and backdoor defense, and robust AI systems.
Mentoring and collaboration
Co-supervise student research in AI, trustworthy AI, and security, mentor students through the full research cycle, and build collaborations across Microsoft Research Asia (MSRA), Princeton University, and universities in China.
Background
Before BIMSA
Before joining BIMSA, I spent 24+ years at Microsoft — including 22 years at Microsoft Research Asia (MSRA) and 3 years in product teams for M365 BizChat / Copilot, the Researcher agent, and Bing Core Search — plus 4 years of startup experience as co-founder and lead scientist of Cognicity, commercializing multimedia watermarking technology. Earlier and parallel work spans privacy-preserving computation, authentication, CAPTCHA, Web systems, multimedia security, and watermarking; a fuller account is in Experience and Publications.
