Research

Research Summary/Interests

Our team studies how blood pressure and heart rate vary in response to stimuli in everyday life, for health surveillance and maintenance.

We use timing according to rhythms (chronobiologic principles) for assessing cardiovascular health, and to detect pre-disease early, so that treatment administration schedules can be optimized to reduce the number of people dying of preventable heart attacks and strokes.

We also explore how solar cycles and changes in the Earth’s radiation environment affect human physiology as their impact has implications for long-term missions in space.

Our extensive archives support research and education in chronobiology as it applies to various fields of medicine.
