In addition to these theoretical contributions, the thesis also contains an empirical analysis of the effect of trading communities on international conflict, and how communities form in a citation network with positive and negative links. He obtained his MA in Sociology (cum laude) from the University of Amsterdam in 2008, followed by a PhD in applied mathematics in Louvain-la-Neuve in Belgium (2013). This has intriguing connections to the evolution of cooperation, suggesting that for cooperation to emerge, groups often split in two opposing factions. Vincent Traag is currently a senior researcher at the Center for Science and Technology Studies (CWTS) of Leiden University in the Netherlands. Besides how to incorporate this in community detection, it also examines the dynamics of such negative links, inspired by a sociological theory known as social balance. One aspect that is often ignored in this field is treated here: links can also be negative, as in war or conflict.

Moreover, it discusses how to asses whether communities can occur by chance or not. Université catholique de Louvain, School of Engineering, ICTEAM, Belgium. Remarkably, only few methods possess this desirable property, and this thesis puts forward one such method. This thesis addresses this issue meticulously, and introduces the important notion of resolution-limit-free. A persistent problem when finding communities in large complex networks is the so-called resolution limit.
