Head of LISC and of research theme MOTIVE. Social simulation, empathy, machine learning, viability and resilience algorithms.

My research interests are in modelling complex systems (social or ecological dynamics) and assessing their properties such as their viability or resilience. I have a long lasting more personal interest in cognitive sciences and more particularly in the concept of empathy. I did my PhD in cognitive sciences (EHESS - Paris VI University) and I got my Habilitation from Clermont University (topic: modelling complex systems). Administrative status: DR1.

Recent projects:

PATRES (2007-2010).
PRIMA (2008-2011).
DISCO (2010-2013).
RESUS (2015-2016)

From June 2010 to June 2014, I have been co-director of the French network for complex systems (Réseau National des Systèmes Complexes).
