Narrative Bio

Dr. Castoro is an Assistant Professor in the Department of Neurology here at Wayne State University. He completed his undergraduate studies at Baylor University. Afterwards, he went to MD Anderson Cancer Center in Houston, TX to study DNA methylation in development and oncogenesis. He then received his medical degree from Oklahoma State University College of Osteopathic Medicine and completed his residency in Physical Medicine and Rehabilitation at Vanderbilt University Medical Center. He then completed his Fellowship at Wake Forest School of Medicine in Neuromuscular Medicine with an emphasis on neuromuscular ultrasound in 2020.

His primary research interest is genetic and epigenetic alterations which lead to peripheral nerve axon degeneration in peripheral nerve disorders. We use both a basic approach and clinical/imaging modalities to study this question with the goal of improving clinical outcomes in patients with peripheral nerve disorders.

His clinical interests are amyotrophic lateral sclerosis (ALS), peripheral neuropathies, Charcot-Marie-Tooth disease, chemotherapy induced neuropathies, hereditary motor neuropathies (HMN) progressive muscular atrophy (PMA) and other neuromuscular disorders.
