I am an experimental psychologist broadly interested in human visual perception. Currently, I work as a Lecturer/Postdoc in the Department of Experimental Psychology with Prof. Uwe Mattler at the University of Göttingen. I teach classes on Behavioral Neuroscience and supervise practical courses in Experimental Psychology.

Until 2015, I was a member of the Department of Cognitive Psychology at the University of Vienna, where I finished my doctoral work on interactions of human visual attention and memory in the perception of natural scenes under the supervision of Prof. Ulrich Ansorge.

Research Focus

I am interested in how the information conveyed in the light that reaches our eyes, through neuronal processing, gives rise to our epxerience of seeing, and how context variables (e.g., our momentary goals, prior experience, or expectations) shape our perception of the world. 

In several projects I studied the mechanisms of selective attention and memory during the perception of naturalistic scenes. I found that our memories determine which aspects of our environment we attend to from moment to moment. This allows us, for instance, to recognize familiar scenes and objects from novel perspectives, or comprehend edited movies despite the abrupt image changes which go along with every cut. Conversely, the selectivity of our attention seems to be key to our impressive memory capacity for visual material.

In my ongoing projects, I aim to understand to which degree our attention and memory determine whether, and how quickly, we become consciously aware of sensory information. Using different perceptual suppression techniques, I present participants with degraded visual stimuli and experimentally gauge the factors enabling the recognition of sensory information. In particular, I am interested in the neural correlates of these perceptual processes in the human brain. For my research, I use behavioral experiments (reaction time measurements and sensory discrimination tasks), eye tracking, as well as functional magnetic resonance imaging. 

About this website

The purpose of Experiment.one on is to provide information about my research, links to additional online ressources, and short discussions of issues I consider interesting and relevant. Please get in touch with me if you need stimulus material, research data or additional information about my work. 

Apart from my research, I am passionate about photography. Here, I share some of the pictures that I took recently. Please ask for permission or license in case you would want to use any of my pictures in your work.
