Chris Yuhao Liu

I am a second-year Ph.D. student in Computer Science and Engineering at the University of California, Santa Cruz, advised by Yang Liu and Jeffrey Flanigan. My research focuses on large language model post-training and alignment. I also work on LLM unlearning.

During my PhD, I have been fortunate to intern at/collaborate with Kunlun 2050 Research, Skywork AI. During my time at Skywork, I was the primary contributor to several open model series, including Skywork-Reward/Critic, Skywork-o1/PRM, Skywork-OR1, and Skywork-Reward-V2.

I love training LLMs.
