Dr. Simon is a pediatric cognitive neuroscientist with a primary interest in clinical translational research. His research focuses on the neural basis of cognitive impairments seen in genetic disorders that produce intellectual and developmental disability and psychopathology. Building on his earlier work on the foundations of numerical competence, Dr. Simon investigates how dysfunction in specific neurocognitive processing systems, such as attention, and spatial or temporal processing can generate a range of cognitive and behavioral impairments. His goal is to develop remedial intervention programs that will minimize such disability. Dr. Simon's current projects center on studies of spatiotemporal and numerical cognition in children with chromosome 22q11.2 deletion syndrome, also known as DiGeorge and VeloCardioFacial syndrome. He is also engaged in similar studies of girls and boys who have sex chromosome aneuploidies. His lab is increasingly exploring the relationships between cognitive impairments, behavioral problems and risk for psychiatric disorders. As part of the NeuroTherapeutics Institute, Dr. Simon leads a grant with Dr. Susan Rivera on the neurocognitive basis of functional impairments in children and adults with the full range of fragile X gene mutations. Besides experimental cognitive processing analyses, Dr. Simon uses cutting edge neuroimaging methods, such as functional magnetic resonance imaging (fMRI), Voxel Based Morphometrics, and Diffusion Tensor Fiber Tracking in order to study the structure, function and connective patterns in the developing brain
