Our work focuses on malformations of cortical development, which are brain disorders that arise when the normal, complex process of development of the cerebral cortex is disrupted. In these disorders, the anatomy of gray matter and white matter within the brain is abnormal, and many patients with these conditions suffer from epilepsy and other neurological problems. We are interested in the structural and functional consequences of cortical maldevelopment, and we study human subjects using neuroimaging, cognitive testing, and clinical neurophysiological techniques. With these methods, we hope to understand better how epilepsy and learning problems arise in the brain, not just in patients with cortical malformations but also in the broader population of individuals whose brain anatomy appears normal.
