My research program involves several focus areas in space and object perception that are tied together by a common perspective that studying action representations is essential for studying visual cognition. One line of research asks how to define the modularity of the visual system with respect to functionally separate but interactive visual processing streams for perception and action. My second line of research examines the neural and cognitive mechanisms involved in spatial transformations of the self and of the external world. Most recently, I have been using virtual environments to examine perception, action, and spatial cognition, and at the same time asking fundamental questions about how virtual environments are perceived. This work involves an active interdisciplinary collaboration with faculty and students in computer science. My approach is to use both cognitive and functional neuroimaging methods to obtain converging evidence for the processes defining visual cognition.
