Welcome to Zhouzi’s Homepage

I am Zhouzi Li (李洲子 in Chinese, how to pronounce), and I also go by Arthur. I am a third-year PhD student in the Computer Science Department at Carnegie Mellon University, advised by Prof. Mor Harchol-Balter. My research focuses on queueing theory and computer system performance, with a particular interest in scheduling problems arising in real-world systems — including cloud GPU resource allocation and LLM inference jobs scheduling.

Before CMU, I received my B.Eng. from Yao Class (IIIS), Tsinghua University.

Recent News - Apr 2026 — Our paper Improving Upon the Generalized c-μ Rule: a Whittle Approach has been accepted by Operations Research!

Research Interests

• Scheduling parallelizable / malleable jobs
• Cluster GPUs allocation
• Scheduling LLM inference jobs
• Optimizing tail performance in multi-server systems
• Applying Bandit theory / Whittle index approach to queueing theory problems

Outside of research, I enjoy playing basketball and tennis. I am also a great fan of music and play the guitar.
