George Pantalos has been floating around, studying blood flow and heart function for forty years. With degrees in both aeronautical engineering and human physiology, Dr. P has been a participant in the study of blood flow in space travel. 

In this episode George shares his research, from his years as a student at Ohio State to his 17year stint in the biomedical engineering faculty at the University of Utah, and 20 years at the University of Louisville. George has also flown 45 times in NASA's parabolic weightlessness simulator aircraft, developing experiments that can be used in Zero G's to study the impact of weightlessness on the human body. I think you'll be as excited as I am to learn about the latest discoveries that George and his research teams have made in the area of human survivability on a multi-year trip to Mars and back.
