István Kovács
I am physics PhD student at Eötvös University specially interested in complex systems. I started my research in 2003 with the supervising of Peter Csermely. Our interest gradually turned from the properties of special proteins through the topology of biological networks to the modularisation of complex networks. Modules are dense groups of network elements, which can be handled together as one element of a higher level network representation of the original network. We worked out a novel method family to identify overlapping modules of complex systems immediately assigning a centrality measure called 'community height value' to each interaction and element. One of our main goals is the identification of specially important elements and regions of networks like module centers and bridges. Due to modularisation the network approach of complex systems is tightly related to the renormalisation approach of statistical mechanics. Our aim is to apply the benefits of this relationship in the study of biological systems as well as in the case of other complex systems.
