Muscle Physiology

Our Research Focus

Our vision is to be innovators and leaders in collaborative neuromusculoskeletal research, education, and clinical translation.

Our mission is to conduct high impact, translational research in the field of musculoskeletal research. Although our core focus is in skeletal muscle design and plasticity, we will continue to explore leading-edge questions in Radiology, Regenerative Medicine, and Rehabilitation.

To achieve this vision and mission we have created a collaborative, respectful and inclusive atmosphere where multidisciplinary experts converge at the forefront of innovation in research and training to advance the knowledge in the field and impact the care of patients with neuromusculoskeletal injuries and diseases.
