Research Interests:

The visual system of the human brain has the remarkable ability to extract useful information from incoming retinal images that in every day life are high-dimensional, complex and locally ambiguous. However, most theories of vision have been developed and tested in simplified domains making their generality unclear. The starting point in my lab is  to understand the computational principles required for visual recognition given the complexities of natural image input. A central idea is that the visual system solves the problems of natural images through a hierarchical cortical organization together with bidirectional processing between areas of the hierarchy.  The experimental challenge is to test and refine such models. My lab has recently begun focusing on the problem of recognizing human body form. Bodies have a natural hierarchical representation in terms of sub-parts, parts and relationships.  We are using behavioral and brain imaging methods to test and refine hierarchical models and computations that support the visual interpretation of objects and, in particular, body form.
