Research Interests
My research investigates structural brain differences in children and adolescents with affective disorders, attention deficit disorder and autism. Including examination of structural MRI differences in discordant twin populations. We are involved in a longitudinal study to characterize very early brain development with MRI in infants at risk for developing autism and infants with Fragile X and Down Syndrome. In addition, in order to better understand structural abnormalities which we and others are demonstrating in children with psychiatric disorders, we are seeking to better characterize the progress of normal structural development and associated cognitive & behavioral development, by MRI, in healthy control populations. This research is done in collaboration with Robert McKinstry, M.D., Ph.D (Radiology), John R. Pruett, M.D., Ph.D. (Psychiatry), Natasha Marrus M.D., Ph.D. (Psychiatry), Josh Simony M.D. (Radiology) John N. Constantino, MD (Psychiatry, Pediatrics), Steve Petersen PhD (Neurology, Radiology) Alex Todorov, Ph.D. (Psychiatry), Deanna Barch, Ph.D. (Psychology); and David Van Essen, Ph.D. (Anatomy).
Secondary to ongoing neurodevelopmental changes, image analysis methodologies need specific validation and potential modifications for use in child populations. We are involved with Dr. Alan Evans (Montreal Neurological Institute) and Dr. Michael Miller and Dr. Tilak Ratnanather’s lab (Johns Hopkins University) on the application of newer image analysis techniques, including automated 3-D, high resolution, warping atlases for child and adolescent populations.
