Dr. Joshua Ewen is a neurologist and director of the Clinical Neurophysiology Laboratory at the Kennedy Krieger Institute and an assistant professor in the Department of Neurology at the Johns Hopkins School of Medicine.


Biographical Sketch:

Dr. Ewen attended Brown University and Tulane University School of Medicine, from which he graduated in 2000. He received training in general pediatrics at Cincinnati Children's Hospital Medical Center and specialized training via a neurodevelopmental disabilities residency (Kennedy Krieger Institute/Johns Hopkins) in clinical neurophysiology/epilepsy (Johns Hopkins). He is currently a neurologist at Kennedy Krieger and the director of the Clinical Neurophysiology Laboratory at Kennedy Krieger.


Research Summary:

Dr. Ewen's research involves the use of neurophysiological techniques to study neurological conditions that affect children and adults. His laboratory uses EEG, quantitative EEG (qEEG), evoked potentials (EPs) and event-related potentials (ERPs). He and his colleagues study conditions including Sturge-Weber syndrome, ADHD, Rett syndrome and adrenomyeloneuropathy.
