Research Interests

My research interests include data privacy and security, privacy-preserving AI, and LLM&AI security.

• Data Privacy and Security We design differential-privacy mechanisms for a wide range of data-analytics tasks, aiming to safeguard privacy in analytical outcomes. Our focus is on solutions that are both theoretically sound and empirically effective.
• Privacy-Preserving AI We leverage privacy-enhancing technologies such as DP, secure MPC, and ZKP to protect data privacy across the entire AI lifecycle—from data collection and training to deployment and inference.
• LLM and AI Security We study security and misuse challenges associated with large language models, including preserving privacy in LLM applications, protecting LLM intellectual property, defending against malicious uses, and using LLMs to enhance system security.
