I’m a mathematician working in Topology. I have a degree in Mathematics from the Pontifical Catholic University of Rio de Janeiro (1985), a Bachelor’s degree in Mathematics from the Pontifical Catholic University of Rio de Janeiro (1985), a Master’s degree in Mathematics from the Pontifical Catholic University of Rio de Janeiro (1986-1987) and a Phd. in Mathematics – Université Paul Sabatier- Toulouse III under the guidance of Professor Gilbert Levitt (1989-1993). I was Visiting Professor at École Normale Superieur de Lyon (1997 – 3 months) and Université d’Avignon (2009- 1 month and 2011- 1 month). I was Vice-Coordinator of the Licentiate and Bachelor of Mathematics courses at IME-UFF in the period 2004-2007, Deputy Head of the Department of Analysis (IME-UFF) in the biennium 2013-2014. My area of interest is Foliations Theory, working mainly on the following topics: topology of leaves of codimension 1 foliations in 3-manifolds, singular foliations in 3-manifolds and classifying spaces associated with foliations. Currently I have also been interested in using topology tools applied to data analysis problems, an area known as Topological Data Analysis. I worked from 2005  and 2007 to 2015 as Regional Coordinator of OBMEP (Olimpíada Brasileira de Matemática das Escolas Públicas) and since 2002 I have been acting as Discipline Coordinator in the Degree in Mathematics and Degree in Physics courses at CEDERJ/UAB, which aims to train teachers in several cities in the State of Rio de Janeiro.
