Research Profile
Dr. Arnold’s research program is focused on translational neuromuscular physiology in the context health, aging, and disease. His lab leverages clinical and preclinical studies to understand mechanisms of biological aging of the nervous system as well as genetic, acquired, and sporadic disorders of muscle and the motoneuron. In particular, he is interested in mechanisms of decline of the nervous system and muscle during aging and understanding ways to improve resiliency of nervous system function across the lifespan.
