This page describes my research activities, which primarily take place in the CORPNET group in Amsterdam.

Computational Network Science

Keywords: network science, corporate networks, social network analysis, computational social science, data science, algorithms

The over-arching theme of my research is computational network science. This means that I am interested in network science from the computational point of view. The main idea behind network science is that by investigating interactions between objects in a dataset as a network, we can better understand the considered data. Moreover, from the network perspective we are often able to reveal patterns and phenomena that are not visible when the mere individual objects are studied. One could see network science as a specialization of data science that focuses on network data. At the same time, network science can be seen as a particular method in complexity research. My research builds around two subtopics, as described below.

  • Computational network science fundamentals

    I first and foremost aim to provide fundamental contributions related to the algorithms, methods and techniques used in network science, with a strong focus on contributions to computer science. This line of research continues that of my PhD thesis titled Algorithms and Analyzing and Mining Real-World Graphs (textpresentation). Topics include: computational aspects of algorithms for analyzing large-scale network data, network visualization, high performance network data processing and large-scale network data management.

  • Knowledge discovery in networks

    The second pillar of my research deals with analyzing, visualizing and mining large-scale network data from a range of domains. The aim is to answer important research questions from these domains by using cutting edge network science algorithms. As of September 2015, I work in the CORPNET project at the University of Amsterdam, where I focus on network-related questions on corporate governance as seen from the domain of political economy. In particular, I work on analyzing corporate and economic networks in which firms are connected based on for example interlocking directorates and ownership.


Sometimes, a project or paper results in a piece of hopefully reusable software, e.g.:
