My main research focus is on the nature and origins of conceptual knowledge: how it arises, the functional organization and response properties of the brain that underlie it, and the contributions of nature and nurture to its development. I investigate the these questions in the areas of quantitative, spatial, and psychological reasoning with young infants, children, and adults using event-related brain potentials (ERPs), optical imaging (fNIRS), as well as behavioral measures.
I also collaborate with others to apply this work to issues in public health, medicine, and education.
