Bill Geisler received his Ph.D. from the Indiana University before coming to the University of Texas. He is director of the Center for Perceptual Systems, holder of the David Wechsler Regents Chair in Psychology, a member of the Institute for Neuroscience and on the faculty of the Biomedical Engineering Program.

Geisler has broad interests within the general areas of vision, visual perception and the evolution of perceptual systems. In his lab, scientific questions are often attacked with multiple techniques: psychophysics (behavior), neurophysiology (in collaboration with Professors Albrecht and Seidemann), image and scene analysis, and mathematical and computational modeling. Current projects are concerned with perceptual grouping, visual search, natural scene statistics, and the neurophysiology of primary visual cortex.

He will give a lecture series in April at the ENS-PSL.
