| The primary goal of my research program is to understand what visual features people use to guide high-level visual behavior in a variety of domains. How do you recognize the faces around you? What makes you decide that a texture is smooth or rough, dry or wet? What information do you use to decide whether someone's gait is confident or not? All of these questions require that we know how the brain represents visual information, a topic I explore using a combination of computational methods, psychophysical experimentation, and electrophysiology. In general, there are three main questions I'm interested in: 1) What information is available in natural images for recognition? 2) What information do observers actually use to make visual judgments? 3) How do representations of the stimulus and visual strategies for recognition change as observers gain expertise? I've explored these questions in multiple domains with a broad range of methodological tools.
