Dr. April Carpenter is an integral member of the Health and Exercise Physiology Department where she is responsible for teaching Anatomy and Physiology as well as other Health and Exercise Physiology related courses. She holds a B.S. in Applied Science from Centenary College of Louisiana and advanced degrees in Molecular and Cellular Physiology from Louisiana State University. Her research interests include the molecular regulation of endothelial function and its impact on all phases of skeletal muscle injury. Dr. Carpenter completed two postdoctoral fellowships – one at Cincinnati Children’s Hospital Medical Center and a second one at the Hospital for Special Surgery/ Weil Medical College of Cornell University. Dr. Carpenter has previously taught courses on Anatomy and Physiology, Human Biology, Medical Physiology, as well as various Environmental Conservation classes.

Skeletal muscle injury is extremely common and few therapies exist to improve or speed repair. The SkM lab studies inflammatory cell regulation of regeneration following skeletal muscle injury in mice. We are particularly interested in understanding how wnt ligands produced by macrophages influence endothelial integrity and expansion.
