Research interests

My research mainly focuses on how graph theory can be used to improve our tools to analyze large-scale interaction networks. For partitioning and hierarchizing networks, I have successively used metrics on graphs, spectral graph analysis, combinatorial properties of some classes of graphs, and simplicial topology of clique complexes. I take part and I promote interdisciplinary cooperation of mathematicians with other domains of science. After having worked with neuroscientists for modelling real neuronal networks, I have developed cooperation for more than fifteen years in the field of social network analysis with historians, linguists, geographers or anthropologists. More recently, I was interested in complexity science, and in particular in complex networks and the link between local and global properties.
I have been director of The Toulouse Social Sciences and Humanities Research Institute during 6 years, Scientific Deputy Director for 5 years at the CNRS Institute for Social Sciences and Humanities and President of the French National Network of Social Science and Humanity Centers during 2 years.
I have lead a project for a Toulouse Institute for Complex Systems Studies. I am Vice-President Treasurer of the Complex Systems Society.

Since July 2023, I have been the scientific coordinator of the Toulouse Initiative Research’s Impact on Society (TIRIS). TIRIS is the project with which the University of Toulouse won the “ExcellencEs” call for projects (PIA 4).
