I am an assistant professor at the Facultad de Matemáticas of Pontificia Universidad Católica de Chile. I am also a member of the Chilean research group on Dynamical Systems. A programme of the dynamical systems seminar of Santiago can be found here.
My main interests are Ergodic Theory, Dimension Theory and Dynamical Systems.
