Dr. Bloomfield gained her B.S. in Biology at Oberlin College (Ohio). After completing an M.A. in Physical Education at the University of Iowa and her Ph.D. in Exercise Physiology at The Ohio State University, Dr. Bloomfield joined the faculty in Health & Kinesiology at Texas A&M in 1993. Her research interests focus on the integrative physiology of bone, with specific reference to skeletal adaptations to disuse, microgravity, caloric deficiency, and inflammation. Dr. Bloomfield is a Fellow in the American College of Sports Medicine and in the National Academy of Kinesiology. Her research has been funded since 1997 by the National Space Biomedical Research Institute, NASA, and Department of Defense. A frequent member of NASA advisory panels, Dr. Bloomfield currently serves on two Institute of Medicine committees advisory to NASA. Since 2016, she has served as Associate Dean for Research in the College of Education & Human Development, overseeing CEHD Research & Development Office staff and functions.
