Dr. Thomas E. Bennett is a human physiologist interested in the effects of weightlessness on human function during space flight.  He has twice flown experiments aboard the Space Shuttle Discovery investigating the effect of microgravity on the cardiac filling cycle using a clinical-type artificial heart and a mock human circulation simulator.  With the tragic loss of the Columbia space shuttle on February 1, 2003, NASA is closing its small payloads division and suspending future student-oriented, university research.  Dr. Bennett is currently developing projects based on sialochemical methods (saliva-based analysis) to study neural, endocrine, and immune system relationships in humans under various conditions, such as, circadian changes, menstrual cycle changes, exercise effects, and stress-related responses.
