Research Abstract:

I am a board-certified pediatric neurologist driven to provide optimal outcomes for all infants at increased risk for neurodevelopmental disability. My research is focused upon the application of advanced neuroimaging techniques, including resting state-functional MRI (rs-fMRI) and diffusion MRI (dMRI), to the study of premature and high-risk term-born children from infancy through adolescence to characterize development of structural and functional connectivity and define the effects of brain injury and early life exposures on neurodevelopmental outcomes. I co-direct the Washington University Neonatal Developmental Research (WUNDER) Laboratory. Our group performs longitudinal studies correlating neonatal and childhood structural and functional connectivity findings with childhood developmental outcomes in prematurely-born infants. We are also performing a longitudinal investigation of the effects of psychosocial stressors, caregiver support and the gut microbiome on cognitive and brain development. This and related work has yielded new insight into early human brain development, while providing a platform for expanded investigation defining the impact of prematurity, brain injury and environmental exposures in high-risk populations via development and application of novel neuroimaging approaches. Our laboratory includes a multidisciplinary group of investigators from the Departments of Neurology, Psychiatry, Pediatrics, Radiology and Neurosurgery, with great emphasis placed on collaboration across disciplines.
