Welcome to my top page!!

 I am Yasuo MUSASHI as a professor at Network Communication, Center for Multimedia and Information Technologies in Kumamoto University.

Born in 1965. Received his M.E. and Ph.D. degrees from Kumamoto Univ. in 1991 and 1994, respectively. Since 1994, had been in Kumamoto Univ. Information Processing Center as a coperative researcher and an assistant professor (1997), was in Kumamoto University, Center for Multimedia and Information Technologies as an associate professor since 2002, was in Kumamoto University, Center for Management and Information Technologies (CMIT) since May, 2014, and has been in CMIT, as a professor, since 2015.  Was a guest scientist of the Johann Wolvgang Goethe Universitaet Frankfurt am Main a half year of 2005 (24.1-31.7.2005). His current research interests are computer network security and developing security incidents detection and prevention systems.

Lauguage: Kumamotonese, Standard Japanese, English, German, Standard Chinese
