About Me
👋 I'm Runlin Lei (雷润林), a Ph.D. candidate at Renmin University of China (graduating June 2027), a member of the ALGO Lab, advised by Prof. Zhewei Wei. My research interests primarily focus on Multi-Agent Systems, LLM Applications, and Graph Machine Learning.
🎓 I earned my Bachelor's degree from Shanghai University of Finance and Economics, where I was advised by Prof. Hongsong Yuan and Prof. Hua Liu.
📧 Feel free to reach out to me via email: runlin_lei@ruc.edu.cn.
News
🚀 I am expected to graduate from Renmin University of China in 2027.6 and actively seeking job opportunities.
🤝 If you are interested in potential collaborations or have relevant opportunities, please feel free to contact me.
