In my research I investigate perceptual processes from the level of simple artificial stimuli up to complex object and scene perception, combining psychophysical experiments and computational modeling. Currently I have three main research foci: First, to develop a computationally efficient, image-based model of early spatial vision. Second, to uncover the critical features observers use in complex perceptual tasks. Third, I explore synergies between machine learning and psychophysics in categorization and, recently, causality.

Accurate measurements need an accurate experimental setup and precise control devices as well as reliable software. My interest is precision psychophysics and so I administer our pool of fine instruments and servers, help improving our psychophysics lab, and then am able to perform exciting experiments.

I am interested in developing better quantitative tools and models to investigate human vision. We have a new toolbox for Bayesian analysis of psychometric functions online at, which is still in testing and development.
My current research focuses on making models for early vision and combining them with eye movement models. For this projekt I work together with the group of Ralf Engbert in Potsdam.
