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.
