Youhuan Li is currently an associate professor in College of Computer Science and Electronic Engineering, Hunan University. He worked as a postdoc in Tencent and Peking University (2018~2021). He received Ph.D. from Wangxuan Institute of Computer Technology, Peking Universiy in 2018, advised by Prof. Dongyao Zhao and Prof. Lei Zou. He was a visiting student in Database System Group in University of Waterloo (2016~2017), working with Prof. Tamer Ozsu. He received B.S. from School of Electronics Engineering and Computer Science, Peking University in 2013.

Research Interests

Youhuan Li recently focus on LLM inference acceleration and LLM-driven data management and analysis. More specifically, he is committed to significantly reducing the inference costs of large language models (LLMs), enabling efficient deployment on general-purpose CPU platforms and resource-constrained edge devices. This initiative empowers diverse applications to harness the advanced reasoning capabilities of LLMs while eliminating barriers imposed by prohibitive expenses and technical constraints.
