Masaru Kitsuregawa has led the development and deployment of big data platforms on the environment and healthcare. Since the early 1980s he has accumulated earth environmental data from many real-time sensors. In 2019, his DIAS system grew to 35 PBs, used by scientists and government agencies around the world for applications such as weather modeling and disaster management. DIAS provides satellite imagery, radar, and river water gauge data for real-time flood prediction and proactive dam discharging. He is building the SFINCS big data platform, with 200 billion medical claims records from Japan. SFINCS enables new discoveries on nationwide statistics for drug usage and time series analysis after operation. These discoveries are being used to improve medical treatments and healthcare system efficiency.
An IEEE Fellow, Kitsuregawa is director general of the National Institute of Informatics and professor with the Institute of Industrial Science at the University of Tokyo, Tokyo, Japan.
