I was fortunate to be advised by Prof. Andrea Arpaci-Dusseau and Prof. Remzi Arpaci-Dusseau (great advisors!) during my Ph.D., working on distributed systems and algorithms, operating systems, and cloud storage infrastructure. My dissertation modernizes consensus protocols for replicated, fault-tolerant cloud services. I also studied file systems and kernel storage stack technologies for new hardware such as persistent memory.

I had a great internship experience at Amazon Web Services supervised by James Bornholt and Andy Warfield, doing a cool cloud storage project for AI workloads.

I worked in the awesome group led by Prof. Harry Xu as a summer research 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 data organization for inherently-structured workloads.
