Current Research

Dr. Wallace conducts several lines of work examining both brain (primarily using magnetic resonance imaging [MRI]) and behavioral development in autism spectrum disorders in collaboration with the Center for Autism Spectrum Disorders at Children's National Medical Center and with the Laboratory of Brain and Cognition at the NIMH.

We are Investigating:

  • Atypical structural brain development in adolescents and adults with autism spectrum disorders;
  • Neuropsychological functioning in children, adolescents and adults with autism spectrum disorders, including both strengths (e.g. savant skills) and difficulties (e.g. executive function); and
  • Adult outcome in autism spectrum disorders
