Research statement: 

In broad terms, I study the capabilities and limitations of the human visual system to process motion information and how that motion information is used to guide eye and hand movements. Experiments measuring the precision with which humans make judgments about visual motion reveal the limitations of motion processing and these data are then used to infer the functional structure of the brain mechanisms involved in the processing of motion information. Applications that utilize dynamic displays must take into account human motion processing capabilities to fully take advantage of the visual system’s strengths and avoid falling prey to its weaknesses. Current research in my lab is focused on how motion is used to segregate the visual environment, the attentional advantages exhibited by avid action video game players, and how moving sounds impact visual motion perception. In addition, other research investigates how human smooth pursuit eye movements respond to complex motion stimuli to shed light on the sensory-motor interface transforming visual motion information into motor commands. Using a high-resolution eye tracker, observers’ eye movements are measured to determine the dynamics of the smooth pursuit eye movement system. These data are then used to determine the underlying computations and processing of the visual motion stimulus that generate the signal to guide human smooth pursuit eye movements. I am also actively studying the attention needed for and the spatial distribution of attention during smooth pursuit eye movements. A new area of research, in collaboration with Dr. Anna Ma-Wyatt at the University of Adelaide in Australia, involves studying reaching/pointing responses to complex visual motion stimuli.
