Elizabeth A. Blaber, Ph.D. is a Research Scientist and the Space Biosciences Task Lead at USRA. Additionally, she is a Principal Investigator in the Space Biosciences Division at NASA Ames Research Center. Elizabeth earned her Bachelor of Medical Sciences (Honors) at the University of New South Wales, Sydney, Australia and her Ph.D. in Molecular Genetics and Biochemistry from the same University. Elizabeth has conducted research at NASA Ames Research Center for the last 8 years and throughout her career has aimed to further NASA’s human research and space biology programs by investigating the role of microgravity on stem cell growth and regenerative functions. Elizabeth is specifically interested in how the cellular and molecular mechanisms of bone regeneration are altered in microgravity as well as the effects of altered load on mesenchymal and hematopoietic stem cell populations and processes during tissue regeneration. These studies propose to uncover the molecular mechanisms driving spaceflight-induced alterations in stem cell-based tissue regeneration to aid in the development of mitigation strategies or countermeasures for long-duration spaceflight.Elizabeth’s research on stem cells has advanced our understanding about the ways that gravity regulates tissue repair and regenerationthrough her use of simulated microgravity and spaceflight studies on the Space Shuttle, ISS and Russian biosatellites.
