Bio

I am currently a third-year Ph.D. student at CMU, advised by Prof. Phillip B. Gibbons. I am supported by Lee-Stanziale Ohana Fellowship. Prior to that, I received my Bachelor's degree from the Department of Electronic Engineering in Tsinghua University (graduated summa cum laude) in 2021, where I was advised by Prof. Dan Pei and Prof. Yongpan Liu. I also worked with Sensor and System Research team in Meta Reality Labs in 2023, and Prof. Julian Shun in CSAIL at MIT during 2020-2021.

Research Interests

Broadly speaking, I design parallel and distributed computer systems in my research, aiming at bridging the gap between theory and practice in the inter-discipline of parallel algorithms, systems and architecture. To be specific, I am recently working on S/A + W (with S/A referring to system/architecture design of heterogeneous-memory systems, and W referring to prevalent workloads in databases and ML/AI).
