Dr. Smith’s research lab is focused on understanding the mechanisms by which skeletal muscle adapts, with an emphasis on the fibrotic processes that are associated with many muscle pathologies including muscular dystrophies. The lab seeks to uncover the relationship between the structure of the extracellular matrix and both the mechanical function of muscle and the regenerative capacity of muscle stem cells. The goal of the lab is to develop strategies to enhance muscle growth and function in order to treat neuromuscular diseases.
