My research and clinical interests focus on developmental psychopathology, with specific emphasis on attention deficit / hyperactivity disorder (ADHD) across the lifespan. I am particularly interested in further investigating and understanding the heterogeneity of ADHD (especially ADHD in the context of autism spectrum disorder as well as medical disorders such as 22q11.2 deletion syndrome). My goal is to use information about the heterogeneity of ADHD to further explore and predict mediators and moderators of treatment outcomes. I direct the Developmental Psychopathology Clinical Research Center here at Syracuse University as well as the SUNY-Upstate Medical University ADHD Clinic (3 blocks from our lab).
