The O’Neill lab studies Attention-Deficit/Hyperactivity Disorder (ADHD), a neurodevelopmental disorder that for many emerges early in childhood.  Although some children who show high levels of inattention and/or hyperactivity during preschool do not go on to develop ADHD, many do go on to receive an ADHD diagnosis at school age; for the majority of these children, ADHD persists through adolescence and adulthood with varying degrees of severity.  Given the high prevalence of the disorder, its chronicity, and associated functional impairment, better understanding of the factors that affect the course of the disorder is needed, as is the development of evidence-based interventions.


Sarah joined the CCNY faculty as an Assistant Professor of Psychology in the fall of 2013.  Her research focuses on the predictors of symptom severity and adaptive functioning among children and adults with ADHD.  She is particularly interested in how neuropsychological factors interact with environmental factors to affect trajectories of ADHD over time.
