Research Summary:    The main focus of my research is the development of numerical cognition from infancy through adulthood.  Specifically, I am interested in how we are able to not only represent different amounts, but also perform operations over these representations.  By studying why and how infants, children, and adults perform mathematical operations, we can learn about the cognitive architecture of the mind- and how this changes as a function of experience, maturation, and culture.
