Research interests


My research on dynamical systems analysis & control/design revolves around three main aspects.

- nonlinear  geometric  modelling and design tools (manifolds, Lie groups, « informative » formulation from symmetries,...)
- interactions  among multiple systems (collective motion, distributed sensing/control, target evolution by coupling,...)
- problems and insights from physics, mainly  quantum physics  systems
