I investigate multimodal integration in motor control and coordination within and between individuals. I use dynamical systems theory and the coordination dynamics framework to understand human adaptive functions, at the behavioural level and at the brain level using non-invasive brain imaging.

● Areas of research:

- Dynamics of perception- action relations

- Multimodal coordination

- Learning

- Interpersonal coordination
