Early works, under the supervision of Ernest Fontich, dealt about the problem of abundance of Arnold difussion in the context of analytic Hamiltonian systems. Besides proving the density of systems with exhibiting such behaviour, several tools were developed that have been used afterwards by several authors.

Related to the problem of instability, the splitting of separatrices has also been studied, both for area preserving maps and Hamiltonian systems of higher dimension.

As a consequence of these last developments, recently a prove has been found of the existence of oscillatory motions in the restricted planar circular three body problem for all values of the mass paramenter, closing a long standing problem.
