Professor at University of São Paulo, with a bachelor's degree in oceanography and MSc and PhD in geophysics, I worked as an Associate Research Scientist at Lamont-Doherty from Columbia University for almost three years, where I also worked as a Postdoctoral Research Scientist for two and a half years. I also have a two-years post-doc from the International Ocean Drilling Project (São Paulo State University, UNESP) and a seven-months post-doc at University of São Paulo. I am specialized in oceanic research, primarily on crustal modeling from gravimetric and seismic data. Some specific points that I have been working on: modeling of salt structures in oceanic basins; modeling of the crust-mantle interface; modeling of the oceanic basement; flexure and isostatic state of the lithosphere; satellite oceanography

FUTURE PROJECTS
VEMA CHANNEL - CRUSTAL STRUCTURE, GEODYNAMIC MODELING AND PALEOBATHYMETRIC RECONSTRUCTION: IMPLICATIONS FOR OCEAN CIRCULATION
In this project, I will investigate the oceanic crustal structure and lithospheric dynamics of the Vema Channel through a comprehensive analysis of residual gravity anomaly and interpretation from geodynamic modeling. I will first calculate the residual mantle Bouguer anomaly of the oceanic crustal regions of the Vema Channel by removing from free-air gravity anomaly the predicted gravitational attractions of water-sediment, sediment-crust and crust-mantle interfaces, as well as the effects of lithospheric plate cooling. I then calculate the gravity-derived crustal thickness constraining them with depth values from available seismic data over the area. The crustal thickness model is then used for the computational geodynamic modeling to study the effects of one to four ridge jumps on melt production and resultant crustal structure. The few previous works over the area have reported a possible aborted ridge, crustal asymmetry and the occurrence of a ridge jumps. Despite of these suggest
