Associate professor at UPC
Research area: Dynamical Systems
PhD in Mathematics obtained at UPC
I obtained my PhD in Applied Mathematics from Universitat Politècnica de Catalunya under the supervision of Tere M. Seara. I have held postdoctoral positions in the Pennsylvania State University, the Fields Institute (Toronto), the University of Maryland, the Institute for Advanced Study (Princeton) and Université de Paris 7 – Denis Diderot (with a Marie Curie Fellowship). I am currently a Juan de la Cierva researcher in the Universitat Politècnica de Catalunya.
My research is (mostly) focused on the analysis of invariant objects and unstable behaviors in Hamiltonian systems of finite or infinite dimension (including Partial Differential Equations) and its applications to Celestial Mechanics.
