Main current projects

COOLNET project (CORESO in French): 5-year project started in 2025, funded with 1 million euros from the Lopez-Loreta Foundation. Let's find new ways to cooperate at large scales, and check them with a video game!
Use the r/place 2022 reddit dataset to characterize early warning signals of transitions in complex human systems, using machine learning techniques. This also provides insights into the structure of massive conflicts and collaborations (are horizontal or vertical organizations more resilient to perturbations?) that lead to many recognizable patterns. We also intend to model the dynamics of the whole canvas with a statistical physics perspective.
Analyse and model the data on the moisture recycling network of the Amazon rainforest, to understand how regions of the forest depend on each other for their survival. Based on this work.
Combine ideas of polycentric governance, multi-layered networks and game theory to find ways to propagate environmentally-positive initiatives at larger scales more efficiently than those of trust-based communities.
