Research
Physical and statistical modeling of particle dynamics in planetary radiation belts, and its application to operational space weather forecasting — currently Director of Space and Atmospheric Sciences at INPE.
What I study
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.
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.
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.
Machine learning for rock physics
Data augmentation and machine learning methods to improve rock-physics models and seismic inversion from well-log data.
