Research areas
What I study
Four connected fronts: radiation belt physics at Earth and Saturn, geomagnetically induced currents, and machine learning applications in geophysics.
CNPq · Brazil
Geomagnetically induced currents
High time-resolution study of GICs across Brazilian territory, and how particle precipitation in the South Atlantic Magnetic Anomaly drives ground-level geomagnetic disturbances.
Van Allen Probes · RBSP
Wave-particle interactions in Earth's radiation belts
ULF and EMIC wave contributions to relativistic electron flux dynamics in the outer Van Allen belt, from doctoral work through ongoing postdoctoral research.
Cassini · MIMI
Radiation belt dynamics at Saturn
Extending radial-diffusion and wave-particle scattering methods developed for Earth to Saturn's radiation belts, using Earth as a physical prototype.
UNICAMP · Petrobras
Machine learning for rock physics
Data augmentation and machine learning methods to improve rock-physics models and seismic inversion from well-log data.
