Director, Functional Neurosurgery & Epilepsy Program; Co-Director, Deep Brain Stimulation; Laboratory Director, Cognitive Neurophysiology & Neuromodulation

Wael Asaad, MD, PhD received his undergraduate degree from Amherst College in 1993, then earned a PhD in systems neuroscience from Massachusetts Institute of Technology in 2001, and his MD from Yale University in 2003. Asaad completed a general surgery internship and neurosurgical residency at the Massachusetts General Hospital. During his residency, he undertook additional training in functional neurosurgery. In 2011, he joined the department of neurosurgery at The Warren Alpert Medical School of Brown University.

Asaad's clinical interests include functional neurosurgery for movement disorders and psychiatric disease, traumatic brain injury, and general neurosurgery of the brain and spine.

His basic science interests focus on the ways in which neuronal circuits in the frontal cortex and basal ganglia underlie visual-motor learning, memory and decision-making, and how a better understanding of these might lead to strategies to alleviate the cognitive aspects of psychiatric and neurological diseases, including traumatic brain injury and stroke.
