|About Me.

I am a postdoctoral researcher in the Theory Group at DESY Hamburg. Previously, I was a PhD student in the Institute of Physics of University of São Paulo in Brazil, where I was advised by Gustavo Burdman. While in graduate school I had the opportunity to be a long term visitor in different institutions. From January to December of 2014, I visited the Center for Theoretical Physics at MIT,  where I was hosted by Jesse Thaler. From September/2015 to May/2016, I was hosted by Géraldine Servant at DESY Theory Group in Hamburg. 
|Research Interests.

Model building and phenomenology of physics beyond the Standard Model, such as composite Higgs, warped extra dimension, and non-minimal dark matter scenarios. Recently, I've been interested in what the early universe can say about our models of particle physics.
