Research Interest: Social Network Analysis Computational Social Science

Introduction

Hi! 👋

In 2023, I joined the Computer and Information Science department at Southwest University (SWU) after obtaining my Ph.D. degree in Computer Science from the Institute of Computing Technology, Chinese Academy of Sciences (ICT, CAS).
In short, 🎓 PKUer -> ICTer -> SWUer.
My research focuses on computational social sciences fields (CSS). Computational social science is a broad field that necessitates interdisciplinary and highly collaborative researchers. You are welcome to email me if you have any promising and challenging CSS research problems.

Currently, I am working on modeling signed social networks (i.e., social networks with both positive and negative links) using graph representation learning.

More recently, I have also been interested in social agents, especially LLM-driven agents for social simulation, human-agent interaction, and broader social computing applications (e.g., Education🏫).
