Biography

Geisler's research interests span a number of topics in vision and visual perception. In the lab, scientific questions are often attacked with multiple techniques: psychophysics (behavior), neurophysiology (in collaboration with Eyal Seidemann), and mathematical and computational modeling. Current projects are concerned with perceptual grouping and interpolation, depth estimation, visual search, natural scene statistics, and the neurophysiology of primary visual cortex.  Geisler is a professor in the Department of Psychology, director of the Center for Perceptual Systems, and holder of the David Wechsler Regents Chair in Psychology.
