I am generally interested in how humans process motion and depth information and how they use this information to interact with the world. I am currently finishing some human neuroimaging studies invesitgating what cortical areas are involved with complex visual motion processing. Two broad areas of research in my lab now involve visual masking and illusory line-motion. In visual masking, a visual stimulus that is clearly perceived when presented alone is less perceivable (or even unperceivable) when a second stimulus is presented nearby in time or space (but not overlapping). In illusory line-motion, a line which is drawn all at once, is perceived to be incrementally drawn from whichever side was nearest to an attentional cue presented just before the line. Understanding these phenomena can better help us understand the role of attention in visual perception.
