Area of expertise

Clinical neuropsychology

Understanding executive functioning has become a research goal and a passion for me. In a broad scope, the elusive nature of this construct intrigues me, thus I have found myself emerged in the study of human behavior and cognitive processing that is "executive" in nature.

Most of my current research is conducted at CORTEX, where we are: (1) developing a theoretical and evidence-based model of executive functioning that we call INTERACT; (2) developing ecological, psychometric and cross-culturally valid instruments to assess executive functioning; (3) exploring the associations between exercise, concussion history and executive functions; and (4) a line of new community-engaged research examining the intersections between brain injury, mental health and addictions. I serve as an Associate Editor in the APA journal Psychological Assessment.
