Welcome to my webpage!

Since August 2013 I am a Professor at the Mathematical Institute of the National Autonomous University of Mexico (UNAM), to whose working group on representation theory of algebras I belong.

I plan to spend my Sabbatical at the University of Köln, Germany, visiting Sibylle Schroll from January to December 2022.

  • My Ph.D. Thesis Advisor was Andrei Zelevinsky :o)
  • I spent 2.5 years in Bonn as a Postdoc of Jan Schröer :o)
  • I was tenured as Professor in September 2017 :o)
  • In March 2021 I was promoted from "Investigador Titular A" to "Investigador Titular B" :o)
  • My CV in Spanish (as of April 2021)
  • My CV in English (abridged; as of July 2020).
  • My Google Scholar profile
  • My MathSciNet profile
  • Möchtest du dein Spanisch üben und mir helfen, mein Deutsch zu üben? Schreib mir und wir können über das Internet sprechen :o)
  • I have started writing a book on Hyperbolic Geometry
  • Online Cluster Algebra Seminar

    Anna Felikson, Misha Gekhtman, Kyungyong Lee, Pierre-Guy Plamondon, Ralf Schiffler, Khrystyna Serhiyenko and I organize a weekly Online Cluster Algebra Seminar (OCAS), continuing the effort started by Misha Shapiro amid COVID-19.

    The seminar runs via Zoom on Tuesdays at 15:00 UTC. Each week a Zoom link and password are being sent to the people subscribed in the OCAS mailing list. (Only people who subscribe receive the OCAS' Zoom links and passwords. You only need to subscribe once to receive all the notifications.)
