Michael J. Joyner MD

Michael J. Joyner, MD is interested in how humans respond to various forms of physical and mental stress during activities such as exercise, hypoxia, standing up, and blood loss.

Dr. Joyner and his team study how the nervous system regulates blood pressure, heart rate, and metabolism in response to these forms of stress. They are also interested in how blood flow to muscle and skin responds to these stressors. These responses are studied in young healthy subjects, healthy older subjects, and people with conditions such as heart failure.
