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.

Information flows through the neurons in our brain in highly distributed, complex patterns, but how do these patterns come into existence? Surely neurons follow simple strategies using local information to find their niche in the marketplace of information that is our brain. And what better place to start investigating this behavior than at a point where we actually know exactly what the input to those neurons is: Early Vision.

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.
