Marguerite Sognier, Ph.D. is a graduate of Jacksonville University, Tulane University and The University of Texas Graduate School of Biomedical Science in the Houston medical center. Dr. Sognier joined USRA in 1997 working onsite at the Johnson Space Center. Her research focuses on the development of countermeasures that will enable future manned space exploration through the development and use of tissue-equivalent, three-dimensional models. Specifically, her research includes: 1) elucidation of the mechanisms of space-induced bone loss; 2) understanding how microgravity conditions contribute to muscle atrophy and; 3) determining the effectiveness of pulsed electromagnetic fields as a countermeasure for muscle atrophy and bone loss. One of several collaborative projects with Engineering include the development of a device to selectively kill bacteria while producing little or no damage to human tissue for future use in space. She is a faculty member at both The University of Texas Medical Branch and The University of Texas Health Science Center and is currently the major professor for a Ph.D. student from UTMB.

In addition to her research at JSC, she is the Director of the Office of Educational Outreach at UTMB in Galveston where she leads the effort to develop and implement novel, exciting educational programs focused on promoting interest in science among students, educators and the community.
