currently serves on numerous advisory bodies and is a member of the NIDCD Advisory Council and the Board of Directors of the American Institute of Wine and Food, The Ambrose Monell Foundation, and The G.Unger Vetlesen Foundation.

John A.Caldwell, Jr., Ph.D., is the principal research psychologist with the Warfighter Fatigue Countermeasures Program at the Air Force Research Laboratory, Brooks Air Force Base, Texas. He has published over 80 articles in peer-reviewed scientific journals and laboratory technical reports. He frequently lectures at safety briefings and scientific symposia, and he conducts operationally-focused workshops on fatigue countermeasures for aviators and industrial personnel. He is a member of the National Sleep Foundation’s Speakers Bureau and Science Advisory Council, and he frequently consults with various organizations on the effects of fatigue on pilots and methods for overcoming the adverse impact of fatigue in the aviation environment. Dr. Caldwell received his Ph.D. in experimental psychology in 1984 from the University of Southern Mississippi. In 1983 he became the assistant director of the Behavioral Medicine Laboratory at Children’s Hospital National Medical Center in Washington, D.C., where he spent 3 years. Afterwards, he spent 16 years with the U.S. Army Medical Research and Materiel Command (USAMRMC) conducting studies on methods of aviator status monitoring and on the effects of medications on aviator performance in specially-instrumented flight simulators and aircraft. In August 2002 he transferred to the Air Force Research Laboratory at Brooks. The focus of his research is to fully understand the effects of sleep deprivation on pilots and to develop monitoring methodologies and fatigue countermeasures for use in the operational aviation environment. Key accomplishments have included the first-ever controlled aviator flight-performance evaluations of the efficacy of dextroamphetamine and modafinil for sustaining performance and the completion of several unique protocols investigating the feasibility of real-time monitoring of aviator physiological activity in flight.

Kong Y.Chen, Ph.D., is a research assistant professor in the Department of Medicine of Vanderbilt University. He also serves as the director of the Energy Balance Core Laboratory. His areas of expertise include advanced designs and modeling techniques of biomedical engineering and developing new methods and improving existing techniques for measuring human energy metabolism, body composition, and physical activity. Dr. Chen is a member of the American Gastroenterology Association, the North American Association for the Study of Obesity, and the American College of Sports Medicine. He was the Young Investigator of the Year for the Vanderbilt Clinical Nutrition Research Center for two consecutive years (1999, 2000) and served as a reviewer for numerous journals. His research is funded by NIH, the Department of Defense, other government agencies, and private nonprofit foundations.
