My research has been devoted to the study of planktic foraminifera as indicators of environmental and climatic conditions in the Late Cretaceous. Among marine organisms, this microfossil group has proved to be an extremely sensitive indicator of paleoenvironmental conditions, and thus of ecological perturbations. My long-term goal is to establish high-resolution records of faunal turnover of the Late Cretaceous in different types of environments and oceanic realms. Achieving a detailed knowledge of planktic foraminiferal populations can provide better understanding of the global Maastrichtian ecosystems and of the nature of the event at the K-T boundary, or any other major environmental crises in Cretaceous history. My research also focuses on understanding the distribution of Cretaceous planktic foraminiferal habitats, and characterizing the ecological strategies of individual species and special biological activities such as photosymbiosis
