About me
My name is Yongjia LEI (้ทๆฐธๅ). I am a first-year Ph.D. student at University of Oregon, majoring in Computer Science. My research interests include Neuro-Symbolic Reasoning and Planning, Graph Retrieval-Augmented Generation, Graph Machine Learning, and Information Retrieval.
My Ph.D. advisor is Prof. Yu Wang at the KIND Lab, School of Computer and Data Sciences, University of Oregon.
Beyond research, I have a deep passion for photography and reading. I also enjoy playing drums and singing, as well as engaging in sports like volleyball and orienteering.
Feel free to reach me at yongjia@uoregon.edu.
