My  background is in carbonate sedimentology and basin analysis, with a focus on the integration of regional, outcrop, and laboratory data. I have experience in facies analysis, sedimentary petrology, and sequence stratigraphy of carbonate systems. I am particularly interested on the controls of carbonate heterogeneity from basin to thin-section scale applying diverse field and laboratory techniques with an special emphasis in deciphering the biogeochemical controls governing the multiscale carbonate heterogeneity of microbial-influenced carbonate deposits.

Since the last years I have been engaged in the understanding of the ‘microbial’ carbonate reservoir fabrics developed in the Pre-Salt hyperalkaline, sublacustrine systems of Brazil and Angola. The principal aim of this project is to develop a new suite of process-based insights into the origin, sedimentology, geochemistry and petrology of spring and lacustrine carbonates in early rift tectonic settings. Unravel the kinetics of the mass-transfer processes in solution, and the dynamics of calcite nucleation producing spherulitic morphologies is one of my current research goals.
