Short CV: 

2014: Master degree in Mathematical and Theoretical Physics from Aix-Marseille University, France.

2017: PhD degree from Toulouse University, France: Collective intelligence in human groups.

Impact of social influence on group performance in uncertain environment: Through experiments and modeling, we analyzed the effect of the quantity and quality of the information shared between members of a group, on collective estimation accuracy when they had very poor prior knowledge about the answer.

Collective decision-making and information integration: We looked at how pedestrians use information coming from their neighbors, to collectively manage segregation tasks in closed environment. We ran several experiments to vary the number of closest neighbors considered, the decision rules, and the arena size. 

Research Interests: 

- What are the determinants of social influenceability in humans?

- Under what conditions can collective intelligence emerge in human groups?

- What are the behavioral and cognitive processes underlying collective intelligence in human groups?
