Alexander Li Cohen, MD, PhD

Principal Investigator

Assistant Professor of Neurology, Harvard Medical School · Director, Laboratory of Translational Neuroimaging and Data Organization Collaborative Service (DoCS), Rosamund Stone Zander Translational Neuroscience Center, Boston Children's Hospital · Data Coordination Director, ARIA Impact Network

Alexander Li Cohen is a physician-scientist and Assistant Professor of Neurology at Boston Children’s Hospital and Harvard Medical School. He received his B.A. in Biology and Biomedical Physics and his M.D. and Ph.D. degrees from Washington University School of Medicine in St. Louis and completed his residency training in pediatrics and child neurology at Mayo Clinic in Rochester, MN.

He moved to Boston Children’s Hospital in 2016 where he completed a clinical fellowship in pediatric behavioral neurology followed by a T32 postdoctoral research fellowship prior to joining the faculty in 2018. He now sees patients as part of the new multidisciplinary Brain, Mind, and Behavior Center and the Autism Spectrum Center at BCH. Dr. Cohen is the Director of the Laboratory of Translational Neuroimaging and the Data Organization Collaborative Service for the Rosamund Stone Zander Translational Neuroscience Center at BCH and the Data Coordination Director for the Aligning Research to Impact Autism (ARIA) Impact Network.

His current research focuses on bedside-to-bedside translation by studying patients with brain lesions that lead to specific symptoms also seen in neurodevelopmental disorders like autism and ADHD and testing ways to modulate these brain circuits with non-invasive neuromodulation such as TMS and real-time fMRI neurofeedback. His work has been supported by the Child Neurology Foundation, the NIMH, the Simons Foundation Autism Research Initiative (SFARI), and the TSC Alliance.
