• Recent development of sensor technology and ICT have enabled collection and acculumation of huge amount and wide variety of biological data. We have been investigating analysis and processing methods of the biological data for supporting clinical diagnosis and health care. For example, development of extraction algorithm of fetal electrocardiogram from maternal abdominal siglnals, and estimation and visualization algorithms of status of autonomic functions based on diverse biological signals.

System development of biosignal anaysis, visualization, and diagnosis.
Development of monitoring and evaluation methods of alertness and sleepiness of traffic driver and workers.
Shift work scheduling based on circadian clock.
