I have expertise in epilepsy, epilepsy neuroimaging, electroencephalography (EEG), and the presurgical evaluation of epilepsy patients. I am the Director of the Penn Epilepsy Center. In addition, I serve as medical director of Penn's Epilepsy Monitoring Unit and Epilepsy Surgical Program. In addition, my research lab focuses on advancing the fields of invasive neurophysiology and neuroimaging to better localize epileptic networks in medication refractory epilepsy patients. It is my hope that improving localization will enable epileptologists to better assign individual patients to the most efficacious therapy, for example, seizure control devices, resective surgery, or continued medical management.
