Hello, I’m Yuxin Yang!

I am a 3rd year Ph.D. student at the University of Southern California, advised by Prof. Viktor Prasanna. My research focuses on Graph Neural Networks (GNNs) and Large Language Models (LLMs), with a particular interest in building and scaling agentic LLM systems. [resume]

Before joining USC, I received my B.E. degree from the Department of Automation at Tsinghua University. I had the opportunity to work with Prof. Muhan Zhang, Prof. Yitao Liang, and Prof. Yilin Mo.

My work is supported by the Capital One Fellowship (2024-2025, 2025-2026).

Other Interests

In my spare time, I enjoy music, piano, and sports activities. I built an interactive webpage on harmony chords while learning music theory. I’m also actively exploring cycling and running routes throughout Los Angeles — check out my Strava!
