About me

I am researcher / data analyst, with a background in physics. After a PhD in physics at ENS Lyon, working within its complex systems institute – aka IXXI – and Post-Docs at INRIA Lyon and MIT Senseable City Lab, I am currently working as a freelance research consultant.

My interests lies in the understanding and modeling of socio-economic systems, social dynamics and mobility, and social networks from a statistical physics viewpoint. I’m involved in projects focusing on human behavior and interactions in cities (as analyzed through mobile phone or transaction data) or social networks (as analysed through Twitter, Facebook, etc. content). The main focus of my current work is detection, analysis and visualisation of scientific research pattern through the analysis of bibliographic data, cf the BiblioTools section of this website.
