Biography

Benjamin Ricaud has a PhD in Mathematical Physics from the University of Toulon France (2007). Previously, he has been a researcher at the Laboratory of Mechanics and Acoustics, Marseilles, the Center of Theoretical Physics, Marseilles, the CEA Cadarache and the LATP (Math Institute) Marseilles.
From 2012 to 2016 he held a research position at EPFL within the LTS2 lab. In 2016 he founded a startup specialized in data science Evia cybernetics. He is now a research scientist back in the LTS2 since January 2018.

His actual research is focused on networks, data analysis on networks and the understanding/tracking of dynamic activity over networks.

Current work

Analysis of graphs and networks
Dynamic activity over networks
Theoretical concepts and methods for the extraction of information from data with a graph structure
