My program of research focuses on the abnormal and normal development of executive function across the life span. My research involves a collaborative, interdisciplinary perspective that prioritizes translational goals and that links perspectives from neuroscience, neuropsychology, and clinical psychology. In particular, I am interested in investigating individual differences that influence the development of the frontocingulate network and related executive functions (i.e., attentional/cognitive control, shifting, updating, inhibition, problem-solving). Our laboratory, the Cognitive and Affective Neuroscience laboratory (www.canlab.org), primarily uses electroencephalography (EEG) methods to study the time course of regional brain activity during executive functioning. We conduct functional magnetic resonance imaging (fMRI) research in collaboration with other local Universities.
