In 2009, I was kindly invited to join the scientific committee of the XXXII Congresso Nacional de Matemática Aplicada e Computacional (CNMAC), the main conference of the Sociedade Brasileira de Matemática Aplicada e Computacional (SBMAC). During this meeting, Sandra Malta and I organized the minisimposium Novos Caminhos em Análise Numérica, where recent graduates doing research in numerical analysis had the opportunity to present their work.

In 2006, I Co-organized the workshop Métodos de Galerkin Descontínuos e Métodos de Elementos Finitos Multiescalas - Teoria e Aplicações, in Florianópoplis, UFSC, Brazil. In 2005, I Co-organized the PreCILAMCE Workshop: Stabilized and Multiscate Finite Element Methods, held at the LNCC.

In August 2004, LNCC held the 1st LNCC Meeting on Computational Modelling, and I was part of the scientific and organizing committee. During this meeting, Frédéric Valentin and I organized a minisymposium on Multiscale Modeling.

I was part of the organizing committee for the 2003 Summer School that took place at LNCC. During this event, I organized a workshop in numerical analysis for PDEs , held at LNCC in February 2003.

I've been involved with the organization of several seminars at LNCC. For a short while, I organized a biweekly seminar named Encontros em Equações Diferenciais e EDPs .

With Frédéric Valentin   and Jaime Rivera , I organized a bimonthly meeting named Jornada de Matemática Aplicada e Computacional ( JMAC ). On May 7 and 8 of 2001, at LNCC,  we had a special JMAC meeting, named " Topics in Turbulence ", when we put  together some of the Brazilian experts in the field.

Again with Frédéric Valentin, I organized the weekly's seminars at LNCC from 1999 until 2002. I was also responsable for the seminar's homepage of LNCC up to 2002.
