Background and Research interests
I am a marine geologist with expertise in slope-to-deep-water sedimentary systems, with a strong background in sedimentology, stratigraphy, structural geology, tectonics and seismic interpretation. Since 2019, I have developed advanced experience in seismic stratigraphy and seismic geomorphology, interpreting multiple subsurface data, including 2D and 3D seismic reflection and well log data in different geological settings (including salt tectonics).
I am particularly enthusiastic about the opportunity to investigate the potential external controls and constraining mechanisms that influence submarine channels, their accumulation patterns and the overall CC stratigraphic architecture in the Magallanes Basin. Furthermore, I am interested in learning more about reservoir-scale heterogeneities, particularly their characterization and modeling, to evaluate their influence on the effectiveness of CO2 storage sites.
I completed my Ph.D. program at Dalhousie University (Halifax, NS, Canada) in April 2024. My Ph.D. research provided new insights into the evolution of the offshore branch of the East African Rift System and its influence on post-Eocene slope-to-deep-water depositional systems. This work highlighted the interaction between tectonics and sedimentary processes (gravity driven processes, mass failures, and bottom currents) along the Tanzanian rifted passive margins, with important implications for geohazard evaluations and hydrocarbon exploration in this frontier area.
