Research Narrative:

My research is primarily concerned with studying how visual attention is controlled in a dynamic world. The brain must efficiently allocate limited processing resources to deal with complex stream of visual information arriving from the eyes. This is the phenomenon of selective attention. How is attention deployed? How do we search for desired objects in the visual field? How do we track moving objects? These are the broad questions which motivate my research. In the context of Sleep Medicine, I am interested in how the global state of the observer (sleep, wakefulness, and circadian phase) affects various aspects of attention (and cognition in general).
