Area of expertise

Clinical psychology

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) examining the role of monitoring systems in the prediction of speech dyfluencies in developmental stuttering; and (3) exploring the associations between exercise, concussion history and executive functions in young athletes using structural and functional neuroimaging, electrophysiological markers, and computerized testing.

Furthermore, I am interested in methods and issues in neuropsychological assessment of clinical populations in North and Latin America. As such, I serve as an Associate Editor in the APA journal Psychological Assessment, and as President-Elect for the Asociación Latinoamericana de Neuropsicología (ALAN). I am also teaching courses in neuroanatomy and clinical assessment.
