Research

Cellular automata: as a model of complex systems. Perturbation, asynchronism, robustness.

Complex networks

This field can be structured into 5 categories :
  • Measure: how to collect reliable and dynamic data on a large scale.
  • Analysis: how to describe the measured graph and extract relevant information.
  • Modeling: once the main properties have been identified, reproducing them in a formal model is crucial to explain them, establish theorems and conduct simulations.
  • Algorithmics: quadratic algorithms are not practical any more on such big graphs, classical problems needs thus to be studied again. In compensation, characteristic properties of those graphs can help design specialized algorithms.
  • Visualization: how to reprensent data associated to node and links for efficient exploration and understanding of the graphs.
Network
I work more specifically on communities, structure, dynamics and networks arising in various (quite different) domains. I have an interest for large datasets.
I have worked on the Vélo'v / Vélib network, and on publication networks.
