I conduct several lines of work examining both behavioral/cognitive and brain development (primarily using magnetic resonance imaging [MRI]) in autism spectrum disorder. The broader goal is to improve the lives and outcomes of people with autism spectrum disorder. By tackling the following lines of research, we are fostering knowledge (e.g., identifying treatment targets for future intervention development) that will achieve this goal. My lab and I are Investigating: 1) Neuropsychological and behavioral functioning across the lifespan in autism spectrum disorder, with a particular focus on executive functioning (i.e., higher-order cognitive skills such as inhibitory control and cognitive flexibility that enable goal attainment and problem-solving) and eating-related behaviors (including both food selectivity/picky eating and overeating); 2) Adult outcome and aging in autism spectrum disorder from both a dimensional (examining subclinical autistic traits in aging) and clinical (examining life course outcomes among those with a diagnosis of autism) perspective; and 3) Atypical structural brain development in autism spectrum disorder across the lifespan
