Yoshihiro Kawahara
Associate Professor<Lab>

Field :
Ubiquitous Computing


Our research group explores architectures and core technologies for ubiquitous computing environment. We develop new sensing modalities and enabling technologies that create a smart and attentive user environment. Specifically, we work on RF energy harvesting sensor networks, wireless power transfer, digital fabrication technology, and new application services that have social significance.


Rie Yamaguchi
Associate Professor<Lab>

Field :
Information Security


There are various problems such as stealing and information fraud in the infrastructure for e-commance. On base of new safe and secure systems applicable to such real problems, we establish information security technologies through next generation personal authentication techniques.

Hidetsugu Irie
Associate Professor<Lab>

Field :
Computer Architecture, Human-Computer Interaction


The basic theme of the laboratory is "computing for the future". The theme involves researches to improve performance, efficiency, and dependability of computers, as well as to achieve never-seen-before services for a person by those efficient computers. Two approaches are cooperating each other here to enrich our life with computing. Features of our researches are as follows; we investigate inside CPUs, and implement free-minded ideas into real systems to experience.


Yoshihiko Hasegawa
Associate Professor<Lab>

Field :
Information Biology, Complex Systems


Biology becomes a frontier field among sciences and unveiling the systems' behavior requires exploitation of recent progress in diverse research fields. Experimental studies have hitherto been played central roles in biology. Instead my laboratory tries to answer many biological riddles by theoretical approaches such as information science and nonlinear physics.

Hideya Ochiai
Lecturer<Lab>

Field :
Sensor Network


Sensor-actuator networking with TCP/IP, is being applied to social infrastructures including smart grid for monitoring, managing and controlling the facilities. We study and develop the architecture for communication, data management, system development and operation for sensors and actuators.
