I am a mathematician, working mainly on dynamical systems and ergodic theory.
I was the Vice-coordinator of the Pós-Graduação em Matemática in 2013-2017.
Some of my collaborators are Andrés Koropecki, Artur Avila, Bassam Fayad, Federico Rodríguez Hertz, Gabriela Ovando, Lucas Backes, Pierre Berger, Rafael Potrie, Sebastián Hurtado, Silvio Reggiani and Xiao-Chuan Liu.
You can find more information about Dynamical Systems in Rio de Janeiro in the DinâmiCarioca webpage and in the UFF's Dynamical System Group. Especial attention deserves our EDAI monthly seminar, which is jointly orgnized by UFF, UFRJ, and PUC-Rio.
