@ Guangzhou, China

I am a graduated student from Sun Yat-sen University, where I was fortunate to be supervised by Professor Shangsong Liang. My research primarily focused on Machine Learning on Graphs and Large Language Models (LLMs). Specifically, my work focuses on: (1) Combining Bayesian graphical models with variational inference to enhance graph representation learning. (2) Investigating memory mechanisms in LLM-based agents. (3) Integrating knowledge graphs to improve retrieval-augmented generation (RAG) and LLM performance for knowledge-intensive tasks.
