Epilepsy Genetics Program | Meet Our Team

Ann directs the Epilepsy Genetics Program at Boston Children’s Hospital as a clinician-scientist, with one hand in the clinic as a pediatric epileptologist and the other hand in the laboratory on a mission to identify the genetic underpinnings of epilepsy. She is a Professor of Neurology at Harvard Medical School, the Diamond Blackfan Chair of Neuroscience Research and the Director of the Neurology Department’s Neurogenetics Program at Boston Children’s.

Ann received her BA in Biology summa cum laude from Harvard University, her MD from the University of Pennsylvania School of Medicine, and her MPH from the Harvard School of Public Health. She completed pediatric training at Boston Children’s Hospital, child neurology residency at the Children’s Hospital of Philadelphia, and clinical neurophysiology fellowship at Boston Children’s Hospital. It was through her rich clinical training that she developed research hypotheses that she pursued as a post-doctoral fellow in the laboratory of Christopher A. Walsh, where she received rich training and mentorship in dominant and recessive neurogenetics and pioneered the study of mosaic (post-zygotic) mutation in developmental brain disorders that lead to epilepsy. Ann started the Epilepsy Genetics Program at Boston Children’s in 2011 to create a translational infrastructure for clinical and research activities focused on epilepsy genetics. She started her independent research laboratory at Boston Children’s Hospital in 2013, integrating clinical research with bench laboratory research focusing primarily on the zebrafish model system.

Ann is a key participant in epilepsy genetics research at the local, national, and international level. She has been part of an international effort to understand the genetics of severe early-onset epilepsies; she served as the Boston Children’s Investigator for the NIH-funded Epilepsy Phenome/Genome Project (EPGP), a national, multi-centered research study, and Co-Investigator for the Epi4K follow-up study. She serves on the International League Against Epilepsy Genetics Commission and chairs the American Epilepsy Society/National Institute of Neurological Disorders and Stroke (NINDS) Benchmarks Stewards Committee.
