Scott M. Smith, Ph.D., leads the Nutritional Biochemistry Laboratory at the NASA Johnson Space Center. The primary goal of this group is to determine the nutritional requirements for extended-duration space flight. Activities include the assessment of nutritional status of crewmembers on missions to the International Space Station (ISS), along with ground-based and spaceflight research efforts.
Smith is the principal investigator for ongoing spaceflight experiments on the space station. His research centers on the role of nutrition in astronaut health, including specific studies evaluating bone loss and vision changes, among others.
He has conducted research on the Shuttle and the Russian space station Mir. Smith also has led several ground-based research projects, including studies of vitamin D in Antarctica. He has published over 100 peer-reviewed publications, chapters and reviews. He has coauthored three books: two textbooks, and another, titled “Space Nutrition,” designed for upper elementary and middle school students.
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, which includes representatives of the five ISS partner space agencies: Canada, Europe, Japan, Russia, and the United States.
He is a member of the American Society for Nutrition, the American Physiological Society, and the International Academy of Astronautics. Smith received a Bachelor of Science in Biology, and a doctorate in Nutrition, both from the Pennsylvania State University.
