Hi, I’m Lingbing, currently an assistant professor at School of Intelligence Science and Technology, Nanjing University. My research interests include knowledge graphs, multi-modal learning, LLMs, and their integration (e.g., MMKG, MLLM, RAG, agentic memory, and multi-agent systems).

I’m actively looking for PhD students, Master students, and research interns. If you’re interested in my work, feel free to contact me!
