She specializes in electroencephalogram (also known as EEG) analysis, seizure localization, surgical planning and neuromodulation for adult and pediatric patients with difficult to control epilepsy. She is nationally and internationally recognized for her work identifying causes of and treatment options for cognitive dysfunction and seizures in epilepsy and neurodevelopmental disorders. Dr. Chu’s team specializes in identifying and developing tools to detect and understand brain rhythms that support complex cognitive functions throughout development, including how these rhythms are disrupted by seizures and neurodevelopmental disorders. Dr. Chu earned her medical degree and a master’s degree in social anthropology from Harvard University. She completed an internship in pediatrics at Massachusetts General Hospital, and then a residency in neurology and child neurology at Massachusetts General and Brigham and Women’s Hospital. After completing two fellowships at Massachusetts General, one in epilepsy and another in clinical neurophysiology, Dr. Chu earned a master’s degree in medical science, focused on clinical investigation, from Harvard Medical School.
