At the most general level, my research program is aimed at identifying the cognitive processes and neural structures that enable and limit our visual representations of the world. For instance, I am interested in: what processes determine whether or not we are aware of a visual object or event, can report its presence, or can recall it later; what mechanisms constrain the number of items we can effectively process at the same time; how higher-level processes such as attention modulate activity in visual cortex; and, why some stimuli (e.g. natural scenes)are processed so quickly and with relatively little effort. We use a variety of approaches to address these questions, including functional magnetic resonance imaging, behavioral methods, and transcranial magnetic stimulation.
