Biography

I work at the SystemsResearch@Google (SRG). My recent research aims to improve memory efficiency for machine learning (e.g., LLM) and non-ML workloads, especially for large-scale systems.

I received my Ph.D. from the University of Wisconsin-Madison (2022), where I worked with awesome Andrea Arpaci-Dusseau and Remzi Arpaci-Dusseau. I received my B.E. from the University of Science and Technology of China (USTC, 2016).

Research

I have a broad interest in systems. My past publications have mainly focused on caching/tiering, memory management, and data-intensive applications.

Emerging Storage/Memory Devices

Tiering/Disaggregation

Data-intensive Applications
