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 Albrecht), and mathematical and computational modeling. For a description of the some recent projects, click the buttons on the left. 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.
