Clinical Interests

Guerriero’s clinical and research interests overlap in epilepsy and critical care neurology. His primary focus involves using EEG monitoring to improve the care and outcomes of pediatric patients in the ICU.  Using EEG and other non-invasive monitoring tools, Dr. Guerriero hopes to deliver timely treatments and interventions.  Through translational research collaborations across basic science and imaging, Dr. Guerriero aims to examine the role of oxidative stress, inflammation and energy metabolism that follows acquired brain injury and contributes to the development of epilepsy and other neurologic sequelae. Dr. Guerriero has additional interests in concussion, refractory seizures, as well as resident education.
