Short Curriculum Vitae
I studied mathematics and physics at the Ruhr University Bochum and received my Ph.D. in mathematics from the University of Leipzig in 2001. In 2003 and 2004, I was a postdoctoral fellow at the Santa Fe Institute and at the Redwood Neuroscience Institute (now the Redwood Center for Theoretical Neuroscience at UC Berkeley). After my postdoctoral stay in the USA I became an assistant professor (wissenschaftlicher Assistent) at the Mathematical Institute of the Friedrich Alexander University in Erlangen. Since September 2005, I work as Max Planck Research Group Leader at the Max Planck Institute for Mathematics in the Sciences in Leipzig where I am heading the group Information Theory of Cognitive Systems. As professor of the Santa Fe Institute I am involved in research on complexity and robustness theory. From September 2009 to November 2013, I was associate professor (Privatdozent) for mathematics at the University of Leipzig. Since December 2013, I am affiliated with the university as Honorary Professor.
