Research Interests

  • frontal lobe and executive function development
  • effect of emotions on face processing and attention
  • neuroimaging in preterm neonates and prediction of outcome

Research Activities

My research investigates the neural bases of cognitive development. Areas of study include development of frontal lobe or executive functions and social cognition using various protocols adapted for children. Current studies use functional MRI and MEG, as well as structural MRI, and include normative series and clinical populations (children with autism and children born very preterm. The research will determine the neural bases, temporal and spatial aspects of the development of abilities, including emotional recognition, working memory, inhibition, set-shifting, and how these cognitive skills emerge with typical and atypical development. We are also following very preterm born infants from birth to determine the impact of very early brain development on later cognitive outcome.
