Analysis of Algorithms

I am an Associate Professor of Computer Science at the Rochester Institute of Technology in Rochester, New York. I earned my Ph.D. at the Carlson Center for Imaging Science at RIT in September of 2003, under the direction of Dr. Jeff Pelz. My work was conducted in the Visual Perception Laboratory, room 2225 of the Carlson Building.

My research interests center on creating computational models of the human visual system, particularly modeling visual attention, visual illusions, and visual perception in the real (non-laboratory) world. These models attempt to explain high-level visual perception as arising from salient environmental stimuli according to the demands of a specific task. To validate and inform these models, we conduct eye-tracking experiments in the Laboratory for Computer-Human Interaction and Performance Support in the RIT CASCII labs.

Some recent and current M.S. projects and independent studies under my supervision include:
