I am a Ph.D. student at the Department of Informatics, the Graduate University for Advanced Studies (SOKENDAI) and National Institute of Informatics (NII). I obtained my Master's degree in Computer Science and Technology from Shanghai Jiao Tong University.

My recent research focuses on the solutions for large-scale graph processing on distributed-memory. Suitable abstractions can often help people understand and solve complicated problems, and my research tries to use domain-specific languages to hide various low-level details when writing distributed graph algorithms, such as parallelism and message passing. We further explore the design of DSLs to provide the compiler with abundant hints to optimize the generated code using domain-specific knowledge.


I am open for job opportunities now. My resume can be found here.
