I am an astrophysicist working as a professor at the Department of Astronomy of University of São Paulo since 2009.

I started my career in theoretical astrophysics, working on radiative transfer techniques using the Monte Carlo method (what is radiative transfer?).

I am author of the radiative transfer code HDUST, that is being used by several research groups for applications in stellar and extragalactic astrophysics. In short, the task of HDUST is, given a physical model of an object (for instance, a hot star surrounded by a gaseous disk), to compute the emergent spectrum and calculate the observables that would be seen by a telescope. This allow the comparison between theory and observations (more details).

In 2006, I started to work more closely on observational astrophysics. My main projects are interferometry of Be stars at ESO's Very Large Telescope interferometer and a long-term polarimetric and spectroscopic monitoring of bright Be stars at the Observatório do Pico dos Dias (LNA, Brazil) (more details).
