Summary

Pouya Tahsili-Fahadan, MD, has been involved in basic and clinical neuroscience research since 2004. He received his MD from the Tehran University of Medical Sciences in 2007. After medical school, he joined Dr. Gary Aston-Jones’s lab at the Medical University of South Carolina as a postdoctoral fellow to study neuromodulation and behavior for 3 years. He did his neurology residency at the Washington University School of Medicine in St. Louis, and, during the last year in the program, he served as the chief resident (2014). He then completed a vascular neurology fellowship at the National Institutes of Health (2015), followed by a 2-year fellowship in Neurocritical Care at Johns Hopkins University (2017). His primary research interests are application of neuroimaging in neuroprognostication and neurological manifestations of critical illness. He is currently a neurointensivist at Inova Fairfax Hospital in Falls Church, VA, Assistant Professor of Medicine at Virginia Commonwealth University School of Medicine, INOVA Campus, and adjunct Assistant Professor of Neurology at the Johns Hopkins University School of Medicine, Baltimore, MD. He is a co-editor of "Neurocritical Care Board Review: Questions and Answers, Second Edition".
