Professional Background

Dr. Hamel is Assistant Professor of Neurology, Pathology and Laboratory Medicine and specialized in the diagnosis and treatment of neuromuscular diseases. Dr. Hamel cares for patients with acquired and hereditary neuromuscular diseases in clinic, with special expertise in myotonic dystrophy (DM) type 1 and type 2 and FSHD. She also performs electrodiagnostic studies in the EMG lab and teaches residents in neuromuscular diseases. She graduated from medical school at the Martin-Luther-University Halle-Wittenberg in Germany, worked as a neurology resident and researcher at the Charité in Berlin before completing neurology residency and a clinical neuromuscular fellowship at the University of Rochester.


Dr. Hamel completed the experimental therapeutics research training fellowship at the University of Rochester. Her research is focused on advancing our understanding of the underlying molecular mechanism in myotonic dystrophy type 1 and type 2. She also studies the progression of disease and evaluates clinical outcome measures and biomarkers. She is involved in several clinical trials and studies involving muscle diseases, with focus on DM and FSHD.
