Associate professor at UB
Research area: Dynamical Systems

PhD in Mathematics obtained at UB (1990)


  • Research fellow of the Spanish Ministery of Science and Education 1983-1986.
  • Adjunct lecturer, Universitat de Barcelona: 1986-90.
  • Associate professor from 1990.

Award of the 1990 Ph, D, in Mathematics with special distinction, Universitat de Barcelona.

His main scientific achievement is the analytic and numerical description of models of return maps near a homoclinic tangency in dimensions two and three.
