Research area
My research field is Network Science, which aims to understand the graph structure of networks and the dynamic processes that take place on networks. Examples of processes on networks are transport of items (IP packets with digitalized information, cars, containers) and diffusion (epidemics, electric current, water flows, human emotions). The Network Architectures and Services Section at the Delft University of Technology contributes to the fundaments of Network Science: we investigate amongst others geometric representations of networks, epidemic spread on networks, spectra of graphs and network algorithms. In addition, we apply our mathematical knowledge to the design, management and control of critical infrastructures, such as telecom networks and power grids. The topic of my chair is Robustness of Complex Networks, i.e. the extent to which complex network are able to deal with perturbations imposed on them. Using mathematical models we try to tackle the following questions: how can we quantify the robustness of networks, how can we identify the most vulnerable parts of the network and how can we mitigate such vulnerabilities. Within TNO I am applying my results to critical infrastructures, in order to make them more resilient towards both failures and attacks.
