I'm a geophysicist working mainly on inverse problems in gravity and magnetics.
Starting February 2014, I'm working as Professor of Geophysics at the Universidade do Estado do Rio de Janeiro, Brazil. I teach the "Intro to Geophysics" courses to Geology students, among others. A typical day at work usually involves a lot of open-source software development, for both research and teaching. My language of choice is Python. I'm one of the founders and main developer of Fatiando a Terra.
In the spirit of open-science, I share all of the research and teaching material online under permissive licenses. You'll find links to source code, images, lessons, etc, scattered around my personal website (look for the icon).
