Publications

I am working with Prof. Andrea Arpaci-Dusseau and Prof. Remzi Arpaci-Dusseau on distributed storage systems and operating systems. My current focus is on modernizing distributed replication protocols under data-heavy workloads. Previously, I have studied file systems and kernel storage stack technologies for emerging hardware such as persistent memory.

I worked with Prof. Harry Xu as a summer intern on scaling and accelerating graph neural networks computation using serverless computing.

I learned a lot from Prof. Shu Yin during my undergraduate study on optimizing file system organization for inherently-structured workload.
