Claus is a postdoc at TU Dortmund University. After doing mathematics, physics and philosophy in Munich and Tübingen, he obtained a Ph.D. in physics with a dissertation on cosmology (LMU Munich 2001). He then worked as a physics postdoc in Oxford for a while. In 2004, he got a second Ph.D., this time in philosophy, where he worked on reasons for action (LMU Munich). In 2004-2005 Claus was a member of the Philosophy, Probability and Modeling Research Group in Konstanz.
Claus’ current research interests are largely in the philosophy of science, where he is particularly interested in how simulations shape present-day science. His project at the Center in Pittsburgh concerns the philosophy of physics, viz. the foundations of physical cosmology. His research at Pittsburgh is supported by the DAAD (German Academic Exchange Service) and the Center, of course. Claus has also interests in Kant and in ethics, public choice theory and voting theory. He is particularly glad to be in the States, when the 2008 presidential elections take place, since he has published on the Electoral College voting system.
