My main research focus is in the area of empirical aesthetics, the scientific study of art and beauty. Our lab is actively investigating the properties that affect the judged beauty of simple shapes such as polygons and texture patterns. We have found that factors like complexity, orientation, and symmetry influence the perceived beauty of these stimuli. Some of my research is the result of a collaboration with my colleague Bruce Liby in the physics department. He and I have published a number of papers on how people estimate the center of objects and are now starting to investigate the perception of fractal patterns. I have also coauthored with Marco Bertamini at the University of Liverpool.
