My name is Zhisheng Qi. I am a Ph.D. student in Computer Science at the University of Georgia School of Computing, working with Prof. Yu Wang at KIND Lab.

Research Interests

• Agentic retrieval-augmented generation (RAG) Reasoning
• Agentic RAG safety (knowledge poisoning) and privacy (knowledge extraction)
• Neural-symbolic agentic intelligence
• Social network simulation and analysis
