She has national and international expertise in conducting clinical trials in adult and pediatric neuromuscular diseases including Duchenne Muscular Dystrophy, Myasthenia Gravis, periodic paralyses, nondystrophic myotonias, myotonic dystrophy and FSHD. She has a clinical research interest in the best treatment of patients with Duchenne Muscular Dystrophy, the course and outcome of pregnancy in women with muscular dystrophies, and sleep disorders in neuromuscular diseases.

Peter CreighPeter Creigh M.D.
Attending Physician

Dr. Creigh completed his neurology residency training at the University of Rochester and is now a clinical neuromuscular fellow. He has a broad clinical interest within the field of neuromuscular medicine, treating all types of neuromuscular diseases. Additional, he is actively involved in neuromuscular clinical research and will be pursuing additional training in experiential therapeutics in the coming year.

Johanna HamelJohanna Hamel, M.D.
Attending Physician

Johanna Hamel, MD completed medical school at the Martin-Luther-University in Halle-Wittenberg, Germany, and worked as a postdoctoral researcher studying visual cognition at the Charité in Berlin, Germany. She completed neurology residency at the University of Rochester in June 2016 and is currently a neuromuscular fellow. Her research interests include muscular dystrophies, in specific myotonic dystrophy type 1 and type 2 and nutritional neuropathies.

Dr. Logigian is Program Director of the Clinical Neurophysiology Fellowship and Director of the EMG lab at the University of Rochester Medical Center. He also serves on the editorial board of Muscle & Nerve, a major neuromuscular journal. His research focus is primarily on electrodiagnostic methods for quantitative evaluation of patients with neuromuscular disorders particularly focal and generalized polyneuropathies. His clinical focus is in evaluation and treatment of patients with acquired polyneuropathies.

Sam Mackenzie Sam Mackenzie, M.D., Ph.D.
Senior Instructor, Department of Neurology

Dr. Mackenzie a clinician-scientist specializing in the treatment of genetic neuromuscular disorders affecting children and young adults. His specific research interests include somatic instability in myotonic dystrophy and loss-of-function conditions amenable to gene replacement therapy. In addition to his work in the lab, he oversees the clinic for patients with limb-girdle muscular dystrophies, performs EMG studies, and attends on the inpatient child neurology service. He completed his MD-PhD training at Upstate Medical University before pursuing residency training in child neurology at The University of Michigan and fellowship training in neuromuscular medicine at The Ohio State University and Nationwide Children's Hospital. He joined the faculty at The University of Rochester in 2021.

His current academic interests include neuromuscular ultrasound and electrodiagnostic studies.

Michael StantonMichael Stanton, M.D.
Attending Physician

Dr. Stanton is Associate Professor of Neurology in the Neuromuscular division at the University of Rochester Medical Center. His clinical interests are in peripheral neuropathy and electrodiagnostic techniques. He is actively involved in teaching neuromuscular fellows in electrodiagnosis and peripheral neuropathy. He is co-investigator for the CMT database which characterizes the clinical and electrodiagnostic features of hereditary neuropathy. He has subspecialty board certifications in neuromuscular disease by the American Board of Neurology and Psychiatry, and in electrodiagnostic medicine by the American Board of Electrodiagnostic Medicine.
