Complexity and Networks

The last decade has witnessed a paradigm shift in the social and natural sciences, fuelled by unprecedented amounts of data collected by various sensors and electronic devices. This shift has led to the gradual disappearance of the boundaries between scientific disciplines - e.g. computer science, statistical physics, applied mathematics, social sciences - and to the emergence of universal tools and theories that allow addressing the complexity around us.

Large-scale data tend to have a relational netare, and their complexity often lies in the web of connection between their elements. Our research group studies the organisation and dynamics of such complex networks. Based on empirical observations in social and brain networks, our research aims at developing computational tools to uncover and visualize information in networked systems, as well as a theoretical framework for dynamical processes on dynamical networks. Applications include: cascades of information in online media, fMRI brain networks, large-scale social networks, human mobility.

Postdoctoral positions available

In collaboration with UCLouvain, we currently have two openings for postdoctoral positions
Research Area(s): Complex Networks and Dynamical Systems
Where: University of Namur and Universite catholique de Louvain
Description: We are looking to recruit two post-doctoral researchers for an inter-disciplinary collaboration between the University of Namur (Renaud Lambiotte) and the Universite catholique de Louvain (Jean-Charles Delvenne). The first project focuses on problems at the interface between data mining, network science and dynamical systems. Areas of interest include finding structures in temporal networks and elucidating the interplay between structure and dynamics in complex systems. The second project focuses on simplicial complexes and networks. The focus will be on extending network modelling techniques to higher-order relationships, and understanding their impact on dynamics. The latter project is in collaboration with Michael Schaub.
How to Apply: For more information, please contact Renaud Lambiotte ( or Jean-Charles Delvenne (
