The primary goal of this group is to determine the nutritional requirements for extended-duration space flight. This involves conducting both operational and research activities. A primary focus includes the assessment of nutritional status of International Space Station crewmembers before and after flight. This protocol has recently been expanded to include an inflight research component – including the collection of blood and urine samples during flight.

Dr. Smith is the principle investigator for an ISS study evaluating the stability of nutrients in foods during extended-duration space flight. Ongoing ground-based research projects include studies of the effects of simulated weightlessness on calcium and bone metabolism, vitamin D supplementation in crews wintering over in Antarctica, and the investigation of dietary and other countermeasures for ameliorating spaceflight-induced changes in human physiology.

Dr. Smith participated in the definition of the current nutritional recommendations for extended-duration space flight, and is Co-Chair of the Multilateral Medical Operations Panel – Nutrition Working Group.

Dr. Smith received a B.S. in Biology from Pennsylvania State University in 1985, and a Ph.D. in Nutrition in 1990, also from Penn State. His postdoctoral research work was conducted at the USDA Human Nutrition Research Center in Grand Forks, North Dakota. He moved to Houston in 1992 to work at the Johnson Space Center.
