Hi! I am Yikang Yue, a computer science Ph.D. student at the University of Illinois Urbana-Champaign, where I am advised by Prof. Jian Huang. I build systems that make LLM agents more accessible by improving the efficiency of agent serving systems and driving down per-token inference cost.

I earned my B.S. in Computer Science at the University of Science and Technology of China (USTC).

My Chinese name is 乐亦康, which means "Happy and Healthy".
When I'm not chasing TFLOPS, you can usually find me reading about computer architecture history, exploring Urbana and Champaign on foot, or cooking something from home.
