■Research Interests

Mathematical Model of Information Space:
Modeling of "information space" that dymanically generates various relations of information-flagments according to user's viewpoints.
Network Webology:
Analysis of link-structures in the World Wide Web.
Network Larning Mechanism:
Acquisition and delivery of recomended information from network communities.
Complex Network Science
My research interests include the structure and dynamics of self-organized networks, the fault-tolerance, the efficient distributed design, etc. in complex network science for wireless adhoc systems and social communications.
