Gregory Russell Samanez-Larkin
Jack H. Neely Associate Professor
Research in our lab examines how motivation, emotion, and cognition influence decision making and health behavior across the life span. Our research is at the intersection of a number of subfields within psychology, neuroscience, and economics including human development, affective science, cognitive neuroscience, behavioral economics, and consumer finance. We use a combination of behavioral and neuroimaging techniques ranging from detailed measurement of functional brain activity (fMRI) and neuroreceptors (PET) in the laboratory to experience sampling measures of experience and behavior in everyday life, wearable measures physical activity and sleep, and real-world measures of financial management. The goal of our translational research is to make discoveries using the tools of basic science that could inform the development of interventions, products, or services that would enhance health and well being across the life span.
In the classroom, I teach quantitative research methods and statistics, applications of neuroscience research for everyday life, and evidence-based course design in higher education.
