Eric Marsh, MD, PhD


Dr. Marsh received his MD from New York University School of Medicine and his PhD in physiology and neuroscience from NYU Sackler School of Biomedical Sciences. After completing his internship and pediatric residency at NYU, he moved to CHOP for a residency in child neurology where he stayed for his fellowship in clinical neurophysiology and completed his post-doctoral fellowship. Hired first as faculty there in neurology and pediatrics, Dr. Marsh is now an associate professor of neurology at the University of Pennsylvania Perelman School of Medicine and CHOP, Clinical Director of the Penn Orphan Disease Center, and Director of the CHOP Rett and Related Disorders Clinic. 

Dr. Marsh has particular clinical interests in developmental epilepsies, neurodevelopmental disorders, and cortical malformations.  His research has focused strongly on the impact of intraneuronal development and altered excitability on epilepsy, analyzing intracranial EEG recordings to better localize the epileptic zone and network, and performing natural history and electrophysiological biomarker studies.  He has also been involved in a number of clinical trials for children with the DEEs, including Dravet, LGS, and Rett syndrome.
