Welcome to my homepage, I am a colombian mathematician mainly interested in studying properties of transfer operators defined on suitable dynamical contexts and their applications in problems related with ergodic optimization and thermodynamic formalism. My research interests deal with the areas of Dynamical Systems, Mathematical Physics and Probability.
My rdős number is 3 (via A. O. Lopes -> R. D. Mauldin -> P. Erdős).
