I am a post-doctoral researcher at the Humboldt University Berlin and the Bernstein Center for Computational Neuroscience. I work with Dr. Martin Rolfs at the Active Vision and Cognition Laboratory.

Research

I study visual perception with behavioral and electrophysiological techniques. My research is about how the brain makes efficient use of its limited-capacity visual system to process the excess of information incoming from the eyes. To this end the brain employs shifts of attention: eye movements and selective processing of particular locations and particular features (like colors or orientations). I investigate these phenomena by measuring how well people can see and how their brains respond to visual inputs.
