Carolina focuses her research on the evolutionary history of fossil birds from Antarctica and South America, addressing patterns of diversification, adaptation, and extinction through geological time. Her work integrates comparative anatomical analyses, particularly osteology, myology, and paleoneurology, with studies of systematics and paleobiology. Morphometric approaches, functional mechanical analyses, and muscular reconstructions are employed to reconstruct the evolutionary history of avian lineages from the Southern Hemisphere, in close association with their paleoenvironmental contexts.
