Description of Research Expertise

Our lab tries to understand how the brain makes decisions. We are particularly interested in the biological mechanisms that allow people and other animals to make decisions when the environment is ambiguous or complicated by the presence of other individuals. We use a broad array of techniques, including single neuron recordings, microstimulation, neuropharmacology, eye tracking, brain imaging, and genomics to answer these questions. Our work is motivated by ethology, evolutionary biology, and economics, with a focus on how specific features of the physical and social environment have shaped the biological mechanisms that mediate decisions. We are particularly interested in why different people make different kinds of decisions. And we are also keen to know why people sometimes make very similar, and sometimes make very different, decisions than other animals do.
