He involved in the research and education of computer architecture, parallel processing, artificial intelligence, natural language processing, distributed processing, and media processing as a professor at the University of Tokyo. He moved to the Institute of Information Security as the dean in 2004, after serving the dean of graduate school of Information Science and Engineering, at the University of Tokyo. He is now the president of the Institute since 2012. He was given the Accomplishment Award from Japanese Information Processing Society, the Paper Award from Japan Society of Artificial Intelligence, the ACM SIGGRAPH’99 Impact Paper Award, the Testimonial of Science and Technology from Tokyo Metropolis, and the Commendation from Minister of Economy and Trade and Industry. He is an honorary member of Information Processing Society of Japan, IEEE Life Fellow, and Emeritus Professor of the University of Tokyo.

Research Themes

Organization methodology of information systems which are the key elements of information society where we can live and work with relief depending on many information systems: secure system organization, high reliable system organization, and dependable system organization of long term. That is, research of system architecture which is the design technology of computer systems by combining many elemental technologies: basic software such as secure operating systems and secure programming, secure Web service organization, intrusion detection, secure network system, and malware analysis.
