About

(No recent photos)

I'm an Assistant Professor of Koshizuka-Lab, Interfaculty Initiative in Information Studies, The University of Tokyo. My research focuses on analyzing the theoretical performance of blockchain-based systems and proposing methods to scale blockchains. Blockchain is one of the distributed ledger technologies and the concept has been well known to the public by Satoshi Nakamoto who invented Bitcoin in 2008. However, a blockchain-based system without a centralized authority must face several scalability limitations to maintain secure, consistent databases across multiple nodes. To solve this problem, I'm studying blockchain-releated technologies, such as off-chain technologies and consensus algorithms.

  I'm also a member of Data Society Alliance (DSA). I'm involved in research and development activities related to Dataspaces proposed by Franklin et al. in 2005, to realize a global, federated data sharing platform. In particular, I focus on trust-related technologies (e.g., quasi-isomorphic cryptography, Watch Tower), which are used in the blockchain ecosystem to guarantee the integrity of data transaction records.

  I participate in the project of Consortium for training experts in statistical sciences that is promoted mainly by the Institute of Statistical Mathematics (ISM) in Japan.
