About Me

I am a computer science Ph.D. student in the ADSL lab at the University of Wisconsin-Madison, advised by Professor Andrea C. Arpaci-Dusseau and Professor Remzi H. Arpaci-Dusseau. My research interest lies in computer systems, especially distributed systems, operating systems, and cloud storage infrastructure.

My current research focus is on modernizing distributed replication protocols for emerging workloads, such as data-heavy replication and wide-area replication. Previously, I have studied file systems and kernel storage stack technologies for new hardware such as persistent memory.

I am working towards graduation this summer, and will join the S3 team at Amazon Web Services as a full-time Applied Scientist starting August 2025. Looking forward to the new journey ahead!

If you don’t mind wasting a few seconds of your life, please take a look at these projects:

Summerset: a distributed, replicated, protocol-generic KV-store framework written in async Rust for unified state machine replication (SMR) research purposes. Summerset is generic to protocols; more are actively being added and evaluated.
MadKV: template of a well-designed KV-store project series for the distributed systems course at my school. Use and extensions for teaching purposes elsewhere are very welcome.
Hux OS kernel: a weekend operating system kernel project built to be minimal and understandable. I documented my development of Hux into a complete set of GitHub Wiki pages.
Garner: demonstrating hierarchical validation for optimistic concurrency control (OCC) on a B+-tree database index.
