About Me
I am fascinated by how effortlessly the brain is controlling our actions and constructs our perception of the world. My research centers on eye movements and how we can use them to understand how the brain makes predictions, how we integrate our experience into our current behavior and whether we can use eye movements as a tool for applied research on image quality.
I am currently a postdoctoral researcher at Justus Liebig University Gießen in Germany and work in the lab of Professor Karl Gegenfurtner.
You can find my publications on Scholar or RG and all data related to these publications on OSF or Zenodo.
Research
 | Saccade-Pursuit Interactions While different types of eye movements are mostly studied in isolation, saccadic and pursuit eye movements interact constantly. Our results suggest that they are different outputs of a shared sensorimotor system. Read more | |
| From abstract to naturalistic stimuli A critical assumption of basic research is that we can generalize results from abstract experiments to understand natural behavior. We tried to directly test that assumption by comparing oculomotor behavior in response to simple stimuli and naturalistic videos. Read more |  | |
 | From the computer screen to the real world While presenting stimuli on a computer screen allows for high levels of experimental control, they lack natural validity. How do we behave in the real or virtual world? Read more | |
| Applied Research When thinking about future VR and AR displays, the visual quality of information is critical. But is it enough to just validate displays perceptually? How does the stimulus presentation affect our actions? Read more |  | |
 | The influence of previous experience How does previous experience influence our behavior? Research on serial dependence effect has shown that our perception is not only influenced by current as well as previous sensory input. Are our actions influenced in a similar way? And what is the relevant information for that? Read more | |
| How aware are we of our eye movements? Eye movements are one of the most frequent movements we perform. But are we actually aware of them? And can we judge how accuratle we perform them? Read more |  | |
 | Beyond Eye movements Vision… We typically study movements towards visual stimuli, but how are they controlled towards your own body? And does it help to move your eyes in the dark? Read more |
