Biography

My research centers on System Security, with a particular focus on safeguarding Critical Information Infrastructures, Cyber-Physic Systems and Intelligent Systems. I am dedicated to improving the reliability, quality, and security of complex systems through advanced techniques such as static analysis, dynamic testing, and AI-powered methodologies. A key aspect of my work addresses deep-seated vulnerabilities in critical domains, including Internet of Things, Industrial Control Systems, Intelligent Unmanned Autonomous Systems, Agentic systems, and AI Infrastructure.

If my research aligns with your interests, please don’t hesitate to reach out to me via email. I would be delighted to explore potential collaboration opportunities.

Research Interests: System Security

Recruiting research interns: LLM/Agent for Software Engineering/Programming Languages/System Security and Safety for LLM/Agent.
