My name is Yuheng Li (李宇恒). I’m an M.S. CS student at UC San Diego, passionate about LLMs and their real-world applications — particularly Agent engineering and post-training (SFT, RL). I’m also actively expanding into search & recommendation systems, with growing interest in generative recommendation.

I grew up in Nanchang, Jiangxi, and I’m now based in La Jolla, California.
