Degree in mathematics from Universitat de Barcelona (1995) and PhD in mathematics from Universitat Autònoma de Barcelona (2001). Post-doctoral stage at Université de Bourgogne (2001-2002). Temporal position at Universitat Autònoma de Barcelona (1995-2006) and a permanent one from 2006 until now.
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.
