Research

I am a Ph.D. student at the Department of Informatics, School of Multidisciplinary Sciences, SOKENDAI (The Graduate University for Advanced Studies).

I have a great interest in parallel computing and graph processing. Currently, I have designed and implemented a domain-specific language for large-scale graph processing called Palgol (Pregel Algorithmic Language), which provides a high-level programming model for users to concisely describe various vertex-centric graph algorithms, and the lightweight abstraction provides high performance guarantee.

I also have research experience in reliable storage systems, erasure codes and bidirectional transformations.
