Developmental neuropsychology is the study of the developing brain and its influence on children's behavior. My research explores basic issues related to nervous system development (laterality, modularity, attentional systems) using experimental paradigms, the development of higher cognitive abilities (language, reading, executive functions) in typical and atypical populations, and applied issues focused on developmental or acquired brain disorders (primarily reading disabilities, attention deficit hyperactivity disorders, and pediatric neurological disorders) in children and young adults. Core research issues have centered on the measurement of change and those nervous system and/or environmental factors that influence developmental variations in these groups of children. Other interests include multivariate approaches to diagnosis, classification and measurement, bilingual reading, and reading instruction.
Currently, my research activities are focused on 1) understanding the diagnosis, development and neurodevelopment correlates of dyslexia/reading disabilities in children and adults, including those with multi-lingual or disabled language backgrounds. This research is based on a number of large, multi-site, federally funded grants that have studied reading interventions and dyslexia/reading disabilities. A component of these studies includes FMRI brain imaging studies of children and adults learning to read. 2) studies of children with mitochondrial disease, a neurogenetic metabolic disorder, and its impact on cognition and adaptive functioning using neuropsychological and brain imaging methods.
My interest in the development of children following acquired brain injury has led in the past to a series of related studies including those of children with brain tumors and their adult outcomes.
