My research activity focusses on 
Dynamical Systems
and Celestial Mechanics. 
 
The main topics are the following: 
·     
Kolmogorov-Arnold-Moser (KAM) theory in 
conservative and conformally symplectic systems 
·     
Development of optimal
estimates in the framework of the Kolmogorov-Arnold-Moser (KAM) theory and
Nekhoroshev theorem 
·     
Dynamics of 
nearly-integrable systems with dissipation 
·     
Stability results for the 
spin-orbit interaction, the Lagrangian equilibrium points, the J2 problem and
the three-body problem in Celestial Mechanics 
·     
Investigation of the
complex singularities of KAM surfaces 
·     
Capture into resonance
and construction of librational invariant surfaces 
·     
Development of numerical
methods for the computation of the break-down threshold of invariant
(rotational and librational) surfaces 
·     
Orbital determination and space debris dynamics 
·     
Applications of dynamical systems to neurobiology 
·     
Space Manifold Dynamics 
(SMD)
·     
Construction of periodic
orbits and investigation of the behaviour of resonances in Celestial Mechanics
