Hello! I’m Zikun Li, currently in my second year as a PhD candidate at the Computer Science Department of Carnegie Mellon University, under the esteemed guidance of Prof. Zhihao Jia. My research primarily revolves around Reinforcement Learning, Large Language Models and Quantum Computing, particularly exploring their synergy with computer systems.

I graduated with a Bachelor’s degree in Computer Science from Peking University in 2021. My time at PKU was enriched by the opportunity to collaborate with Prof. Tong Yang on developing advanced algorithms for data stream mining.
