My research uses new Magnetic Resonance Imaging (MRI) and brain monitoring techniques to identify how early-life brain injury, clinical illness, and social determinants of health impact neurodevelopment in newborns at high risk for developmental disabilities. I am also interested in understanding long-term developmental trajectories in children with early-life brain injury. Understanding what factors impact brain development may point to new strategies for promoting long-term brain health in high-risk infants.

The Disconnectome in Neonatal Brain Injury and Associations with Neurodevelopmental Outcomes
Infants with brain injury, such as term infants with hypoxic-ischemic brain injury and preterm infants with white matter injury are at increased risk for neurodevelopmental problems. However, there is considerable variability in outcomes amongst these infants making it difficult for us to predict their long-term outcomes. This project aims to understand how neonatal brain injury in term-born infants impacts structural brain connectivity (the Disconnectome), and how this relates to neurodevelopmental outcomes. This may allow for more accurate identification of high-risk infants who may benefit from early neurodevelopmental interventions.

Intersection of Social Determinants, Brain Injury and Brain Dysmaturation, and Associations with Neurodevelopment in Children with Congenital Heart Disease
Infants with congenital heart disease are at increased risk for brain injury and abnormalities in brain maturation (brain dysmaturation) that contribute to an increased risk for neurodevelopmental problems. However, social disparities have also been linked to poorer childhood neurodevelopmental outcomes. Children with congenital heart disease in whom these factors intersect may be particularly vulnerable. This project aims to understand how social disparity modifies the relationships between brain injury, brain maturation and neurodevelopmental outcomes in children with congenital heart disease. There will be a specific focus on identifying the specific pathways through which social determinants impact neurodevelopment, which may point to potential interventions to more equitably promote brain health in this population.
