Research Interests

My research aims to create an integrated understanding of the behavioral and neural dynamics of executive function over development.

Research statement

I study the development of executive function using a combination of behavioral, neural, and computational methods. The primary questions I address in my research center around how perception and action are integrated in a controlled, goal-directed fashion. Specifically, I use dynamic field theory, which is a class of dynamic systems models, to formally integrate behavioral and neural processes. The primary neuroimaging technique I use in my lab is Near-infrared Spectroscopy (NIRS) which allows for measuring functional neural activation in infancy and early childhood.
