Research Projects

NSFC

National Natural Science Foundation of China · Young Student Research Program

Intrinsic Security Defense Technologies for LLM Agents

Principal Investigator

Focusing on intrinsic security risks in LLM agents, this project develops a three-layer active defense framework spanning the full perception–reasoning–action pipeline.

SRTP

SRTP National Innovation Project

Universal and Harmless Model Watermarking

Principal Investigator · Completed with Excellence

This project developed domain-embedding-based model watermarking that reprograms a target model into an owner-controlled latent space. It preserves harmlessness while remaining robust against a range of model-removal attacks, and received the Best Creative Project award at the National College Student Innovation Annual Conference—one of only 12 projects nationwide.

DualMind: Towards Understanding Cognitive-Affective Cascades in Public Opinion Dissemination via Multi-Agent Simulation

Enhao Huang, Tongtong Pan, Shuhuai Zhang, Qishu Jin, Liheng Zheng, Kaichun Hu, Yiming Li, Zhan Qin, Kui Ren

An LLM-driven multi-agent simulation framework that jointly models transient affective responses and persistent cognitive beliefs in public-opinion propagation. Evaluations on 15 real-world crises show that it reconstructs opinion trajectories more faithfully than existing simulation baselines.
