Research Summary

Sakurada Kazuhiro

The Open Systems Information Science Special Team is conducting interdisciplinary research that integrates medicine, experimental biology, psychology, information science, and physics to realize preventive medicine based on the root causes of disease.
To address the root causes of disease, we have developed new inference frameworks that focus on aging and interoception, interpret the life course as a process, and enable prediction. One such framework is the development of organism mechanics, which interprets and predicts changes in biological function as movements in a state space and as interactions within a message field.
