Request Expert

He is an expert in Fundamental Astrodynamics, having more than 10 years of academic experience working in satellite orbit design in the presence of perturbations (gravitational, atmospheric drag, solar radiation pressure). He has also intensively work in the relative motion of satellites, focusing on long-term formation-keeping by optimal formation configuration/re-configuration.

His background formation is that of Mathematician, skilled in the theory of dynamical systems, Hamiltonian mechanics, perturbation theory.

He has more than 13 years teaching experience in: Mathematics, Theoretical Mechanics, Astrodynamics, fundamentals of Robotics.
