I am a researcher at IBM Research - Tokyo in Yamato, Japan. Since 1997, I had worked around advanced reflection technologies in Java (a.k.a. OpenJava and Javassist), applied the technologies to aspect-oriented development for distributed computing (a.k.a. Addistant) at University of Tsukuba, Japan. Just after receiving a PhD degree in Engineering from the university in 2002, I joined IBM Research in Japan. There I shifted my research focus to more application side, Web, and had worked around XML and Web Services, mainly dedicated to WebSphere Application Server products of IBM. I also led the Java zone in IBM developerWorks Japan during 2002-2003. Since 2005, we started Dynamic Scripting Languages projects, especially for PHP. Parts of the results have been published at major academic conferences like ICWS, Middleware, POPL, and WWW. Also, some research results have been transferred to IBM Software Group as the core technologies of a PHP implementation on Java for products such as WebSphere sMash, CICS and MessageBroker.
Recent focus is on the inter-disciplinary engineering between business process modeling and analytical decision management, frugal approaches for intelligent transportation systems, and Linked Open Data, especially focused on the purposes of Smarter Cities.
