Nadine works on phenomenological and theoretical reconstruction of premature embryogenesis of Deuterostome animal models. This integrative approach of morphogenesis and the cellular differenciation underlying the development of the organism is grounded in a quantitative analysis method based on the automated treatment of multimodal and multi-scale imagery in vivo and in toto. These strategies are available on the BioEmergences Platform.

Lena Sanders is a geographer and Director of Research at CNRS. She holds a double degree in Statistics (Institut de Statistiques des Universités de Paris – ISUP) and in Geography (Université Paris VII). Her research focuses on the urban system dynamics and the recomposition of the metropolitan space, building on methods of spatial analysis and the theoretical apparatus of complex systems modeling.

José Halloy is Professor of Physics at Université Paris Diderot. His research pertains to the transition from individual capabilities to collective behaviours at different level of living and artificial systems as population of cells, organisms, robots or collections of networked machines. The aim is to understand the design principles and the dynamical properties of such populations that can produce emergent or self-organised properties at the collective level. His current research deals with new forms of collective intelligence in natural and artificial systems.
