Curriculum Vitae

Currently I’m a Ph.D candidate at SOKENDAI under supervision of professor Eiichiro Kokubo and an Associate Researcher at the National Astronomical Observatory of Japan.

You can see a brief version of my inside-and-outside-of-academia experience here.

For a list of my academic publications, you can click here.

If you are interested in some of my talks and presentations, come here.

Finally - but definitely not least - , some outreach activity can be seen here (all in portuguese).

A PDF version of it can be accessed here
