Networks have become a general concept to model the structure of arbitrary relationships among entities. The framework of a network introduces a fundamentally new approach apart from `classical' structures found in physics to model the topology of a system. In the context of networks fundamentally new topological effects can emerge and lead to a class of topologies which are termed `complex networks'. The concept of a network successfully models the static topology of an empirical system, an arbitrary model, and a physical system. Generally networks serve as a host for some dynamics running on it in order to fulfill a function. The question of the reciprocal relationship among a dynamical process on a network and its topology is the context of this Thesis.

Born on February 18, 1980 in Berlin, Germany. After graduatingfrom the Technische Universität Darmstadt in 2005 with a diplomain Physics, he wrote his dissertation under the supervision ofProf. M. Porto. He received his doctoral degree in December 2008and continued as a postdoctoral fellow of Prof. J. Klafter at theUniversity of Freiburg.
