At each stage of my trajectory I have interacted with people who supported me in different ways:

Currently...

Senior scientists like Reinaldo de Carvalho, James Annis, Scott Dodelson, Huan Lin and Juan Estrada contribute with advice, invaluable discussions, questions and insights.

Young scientists and post-docs like Jeff Kubo, Ribamar Reis, Hee-Jong Seo and Francesco La Barbera add a special contribution to all that and with them I share work, knowledge and experience.

I am a participant of the clusters and weak lensing working groups at Fermilab and of the clusters working group of the Dark Energy Survey collaboration. In these groups I interact as well with other scientists like Risa Wechsler, Michael Busha and Brian Gerke (Stanford), Timothy Mckay and Chris Miller (Michigan), Eduardo Rozo (Chicago), Albert Stebbins, Elizabeth Buckley-Geer, Sahar Allam and Tom Diehl (Fermilab).

Previously...

During my master studies I worked with Elisabete de Gouveia Dal Pino (my thesis advisor) and Jorge Horvath, at the University of São Paulo. I also counted on advice and friendship from other experienced scientists like Denise Gonçalves (Valongo Observatory, Rio de Janeiro) and Ignacio de la Rosa (Instituto de Astrofisica de Canarias).

Earlier...

As an undergrad I started doing research in the cosmology working group at the Federal University of Espírito Santo. My advisors were Sergio Gonçalves and Julio Fabris. I also worked with Ennio Candotti in outreach projects.
