Networks are pervasive in nature and technology, and as such form a relevant framework for our understanding of complex systems. Ecological systems, the brain, as well as human communication and transportation systems are but a few examples thereof. Network studies have revealed striking underlying laws and patterns which apply to a vast range of networks, in nature and in society. We develop novel ways to unveil the structural organization and functional patterns in complex networks with a broad range of applications. In addition to data-driven analyses, we are involved in international efforts to further our fundamental mathematical understanding of networks.
