In my PhD thesis I dealt with the ontological commitments of our talk about numbers. I wrote my thesis in the Nominalizations project at the University of Hamburg (led by Benjamin Schnieder). During my PhD studies I also stayed about one year at the MIT in Cambridge (MA) to work with Stephen Yablo. Before joining the Nominalizations project in 2011, I studied at the University of Constance, the ILLC in Amsterdam, and the Humboldt University in Berlin. I received my master's degree from the University of Constance. In my master's thesis, which was supervised by Tobias Rosefeldt and Franz Huber, I dealt with the influence of vagueness on our degrees of belief. You can find a more detailed CV here.
