Research interests
I am interested in the psychophysical and neural mechanisms that underlie human motion and depth perception at a systems level. My work has focused on the ability of human observers to extract information about the motion of objects--in particular, through depth--based on a variety of visual cues. This is critical to understanding how the visual system adepts to changing environments, and challenging situations in which the preferred visual information may not be available. To this end, I have used mathematical constructs, such as ideal observer models and biologically constrained computational models, to study how the visual system extracts and utilizes various sources of motion and depth information. Complementing this work is a recent focus on human neuroimaging, and in particular, the study of connected networks that mediate the detection of object motion in visually complex situations, such as observer motion. By coupling a mathematical understanding of the behavioral mechanisms with a systems-level understanding of neural mechanisms, new insights into the complexity of sensory processing in the human brain can be probed.
