One of my major research foci is in the genetic basis of psychiatric and neurological disorders. I am currently involved in studies to dissect the genetic etiology of attention deficit hyperactivity disorder (ADHD), autism, chiari type I malformations, essential tremor, and neural tube defects. Additional research foci include genetic modifiers of sickle cell disease, and genetic contributions to birth outcomes, particularly among African American women.
