Research Description

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.

Building Remodeling Projects

Click on the title to check out these pictures from the classroom remodeling project in the basement. A second project to replace the elevators will begin in September. Beginning with the freight elevator, each elevator will be out of service for three months. To get quickly from one floor to another, and improve your fitness, we will encourage the use of the stairs. The repainting of the northeast stairwell has been completed, and the painter is starting on the southwest stairwell.
