Interests

My research focuses on the theory of differential equations in the complex domain. I have worked in three main lines:

a) analytic and topological invariants of singular holomorphic foliations in the complex plane,

b) description and classification of the set of global singular foliations on the complex projective plane fulfilling a Zariski  closed property as being convex, Galois or having a flat dual web,

c) bifurcation of critical periodic orbits in families of real centers in the real projective plane.
