I am a biomedical engineer with specific training and expertise in imaging science and sensory-motor neuroscience. In recent years, I have focused on developing innovative and reliable functional connectivity-based parcellation methods to study brain organization. Using these methods, we have demonstrated that abnormalities in the functional segregation of limb control within the motor system and in the intrinsic synchronization between motor and visual systems are related to the severity of social deficits in school-age children with autism. As part of my NIMH funded Career Development Award (K01 MH109766-01), I am extending these findings to study the longitudinal development of visual-motor synchronization and hand-eye coordination in infants at high risk for autism to determine whether the abnormalities observed in school-age children come online before or after symptom onset. I am also collaborating with others in the department to develop movement-based intervention methods for enhancing visual-motor connectivity necessary for imitating and learning from the actions of others.
