Work

I apply Information Theory to reseach on human consciousness.

Several influential papers claim that unconscious processes convey more information than conscious processes. But their evidence is based on a problematic methodology. I re-analyze their results and conclude that, contrary to the claims, there seems to be no evidence that so-called 'unconscious' processes convey more information than conscious processes.

I investigate in the context of confidence-weighted majority voting how much information participants can consciously access.

CV

I studied Human-Computer-Interaction (B.Sc.) and Psychology (B.Sc.) in parallel followed by Informatics (M.Sc.) at the University of Hamburg. Starting with my master thesis I worked at the Theory of Machine Learning and Experimental Cognitive Science groups in Tübingen. In 2022, I finished my dissertation on statistical flaws in unconsciousness research and theoretical bounds on ensemble performances. Now, I continue to combine these two topics and investigate how the visual system integrates ensemble information.

Mediation

I am currently (March to August 2022) being trained as a certified mediator (IMI Mediator) and offer mediation in the context of university work groups. If you think of a conflict in your work group and wonder if mediation could help, visit me at my office hours or send me a short email.
