Chelsea Bahney, PhD
Assistant Professor


The focus of my laboratory is to develop novel translational technologies that promote musculoskeletal regeneration by recapitulating embryonic development and repair. My background includes training in both Chemical Engineering and Cell & Developmental Biology, and the laboratory is modeled to reflect this interdisciplinary approach to research. Our work aims to utilize biologically modified polymers to promote a sequence of biological milestones that parallel native repair. The long-term goal of our research is to solve problems that will have a direct and significant impact on human health.
Current Projects:
  • Tissue engineering strategies to promote endochondral bone regeneration
  • Transdifferentiation of cartilage to bone during fracture repair
  • The role of the nerve in fracture repair
  • Polytraumatic Injuries: How brain trauma influences fracture healing
