Trustworthy Data Science and AI Lab

Rigorous Science for
Trustworthy AI

We study the security, privacy, and reliability of AI, spanning large language models, autonomous agents, federated learning, and data markets. Our goal is to develop rigorous foundations, practical methods, and deployable systems for trustworthy AI.

What We Work On

We tackle trustworthy AI at three levels — foundational theory, algorithm design, and real-world system deployment.

Privacy Tech Foundations
Building the theoretical and algorithmic foundations of privacy-enhancing technologies — differential privacy, MPC, TEE, federated learning, and machine unlearning — from rigorous guarantees to deployable systems.
AI Security & Safety
Studying how LLMs and autonomous agents can be attacked and defended — covering jailbreak, prompt injection, backdoor attacks, and adversarial risks across the full AI stack.
Trustworthy Data Systems
Designing data pipelines and AI systems that are auditable and reliable — through RAG reliability, membership inference, transparency analysis, data markets, and multimodal safety evaluation.
