I'm a geophysics PhD student working on potential field inversion at the Observatório Nacional, Rio de Janeiro, Brazil. I'm currently a member of the IAG Joint Working Group JWG2.8: Modeling and Inversion of Gravity-Solid Earth Coupling. My interests are inverse problems, open source software, and Northern Shaolin Kung Fu.

Research interests

  • Potential field modeling in spherical coordinates
  • 3D potential field inversion
  • Inverse problem methodologies
  • Scientific software development
  • Different ways to incorporate geologic information into geophysical inversion
  • Teaching inverse problems
