My main research line focuses on the study of modern and fossil land snail shell assemblages via multidisciplinary approaches such as isotope geochemistry, taxonomy, taphonomy, paleoecology, morphometrics and aminoacid dating. I use all these proxies to attempt to reconstruct past environmental and ecological conditions, to estimate the quality and fidelity of the fossil record, to better understand organism-environment interactions, and to predict the ecological response of land snails to habitat perturbations. I am mostly interested in low-latitude oceanic settings, which are highly sensitive to human impact and global change. My primary field-research areas include the Canary Archipelago and The Bahamas.
Other active research lines I work on include (1) isotope geochemistry of human and animal bone collagen (implications in reconstructing the paleodiet of ancient human populations), (2) stable isotope composition and concentration of indoor and outdoor atmospheric CO2 (implications in the environment and global change), (3) predator-prey interactions between marine gastropods (implications in the fossil record of predation), and (4) isotope geochemistry of aquatic mollusk shells (implications in reconstructing the paleoenvironment in marine and freshwater realms).
