*Education* · *PhD* *2001* : B THON, University Paul Sabatier Toulouse, France *Sensorimotor learning, verbal instructions, language- sensorimotor interactions* · *Post-Doctorat* *2002-2005 :* JAS KELSO, Center for Complex Systems and Brain Sciences, Boca Raton USA *A huge dive into Coordination dynamics, phase transitions, EEG, multimodal dynamics, social coordination. I was lucky to attend several full semester courses from the PhD training program in Complex Systems: Time series analysis (Steve Bressler), Dynamical systems (Richard Voss), Theoretical neurosciences (Viktor Jirsa), Stochastic processes (Viktor Jirsa).* · *Post-Doctorat* *2005-2008 :* B BARDY, Enactive and Skills IP European projects *Skills, virtual reality, juggling pattern, transfer of skills, postural coordination dynamics* · *Habilitation* *2012* : La dynamique des patrons de coordination. Mécanismes impliqués dans l’intégration multisensorielle et les interactions interpersonnelles. *Research* I investigate pattern formation/ coordination dynamics in cognition, human movement and perception. Main topics: Multimodal coordination dynamics, Social neuroscience. *Multimodal coordination dynamics: Dynamical binding between the senses in human movements.* The brain has the fascinating capacity to put together different senses. I inquire how the senses and movements are bound together and how this ensemble evolves in time. The approach consists in seeking abrupt qualitative changes in behaviour. Why so? In the vicinity of important and sudden changes, the entire evolution of the system under consideration follows the behaviour of one or few variables; these purported variables give us all the information we need (Haken 1988; Kelso, 1995). Coordination dynamics is a theory that seeks to explain how patterns arise and change every second and milliseconds, and how to choose the effective variables to model a complex system. Kelso, J.A.S.
