Overview

Research in our lab examines how individual and age differences in motivation 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 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 in everyday life.
