Work

I apply Information Theory to reseach on human consciousness. I show that, in the overwhelming majority of cases, humans can report the same amount of information that is present in their behavior — which is evidence against the scary notion of unconscious influence.

I further investigate measures of metacognition and their implications for group behavior since interactions in a group depends on whether individuals can appropriately indicate when they are certain or not.

If you are a student in Cognitive Science or Computer Science and want to work with me for your B.Sc. or M.Sc. thesis, check out my currently available topics and send me an email.

CV

I studied Human-Computer-Interaction (B.Sc.) and Psychology (B.Sc.) in parallel followed by Computer Science (M.Sc.) at the University of Hamburg. I then did my doctoral degree (Ph.D.) in the Theory of Machine Learning and Experimental Cognitive Science groups in Tübingen in 2022. Since then I work as a postdoctoral researcher on methods in unconsciousness, metacognition, and group research.

Mediation

I am trained as a certified mediator (IMI Mediator). If there is a conflict in your work group, I am happy to create a safe environment for you and the people involved so that you can find a fair solution. Send me an email to find out if this can help your group.
