Bio
I am currently a fourth-year Ph.D. student at CMU, advised by
Prof. Phillip B. Gibbons.
Prior to that, I received my Bachelor's degree from the
Department of Electronic Engineering
in Tsinghua University
with highest honor in 2021, where I was advised by
Prof. Dan Pei and
Prof. Yongpan Liu.
I also worked as a Research Scientist Intern in Meta Reality Labs in 2023,
and with Prof. Julian Shun
in MIT CSAIL during 2020-2021.
Research Interests
My research focuses on algorithm engineering and computer system design for modern and/or future hardware,
aiming at bridging the gap between algorithmic theory, and system and architecture design.
To be specific, I am recently designing heterogeneous-memory systems and algorithms for databases and AI/ML,
featuring principled (i.e., theoretically-guaranteed and practically-efficient) techniques.
