Research & Initiatives

We conduct epidemiological research aimed at improving public health.

From the perspectives of acute care medicine, forensic medicine, and neuropsychiatry, we investigate the incidence and trends of diseases using demographic variables such as gender and age, as well as medical information and environmental indicators (e.g., temperature).

Currently, we are also engaged in research in the following fields:

Emergency Medical Field: Mental Health × Forensic Medicine × Acute Care Medicine
Space Exploration Field: Mental Health × Manned Space Missions
