Activities
My research is based on Early Cretaceous calcareous nannofossil assemblages, as well as their relationships of abundance to surface water fertility and productivity as a way to examine paleoceanographic changes in the South Atlantic Ocean. We are currently looking at these nannofossil assemblage dynamics to explore the nature of cyclic sedimentation in the Oceanic Anoxic Events (OAEs) and Cretaceous Oceanic Red Beds (CORBs). Thus, my research interests relate to advancing coccolithophore studies about ecosystems, climate change, and mainly biogeochemistry. I also study the impacts of Large Igneous Provinces (LIP) Paraná-Etendeka in the Early Cretaceous marine phytoplankton assemblages. In addition, studies about this LIP in the Unesco Geopark Caminhos dos Cânions do Sul were developed.
