My research focuses on theoretical and applied aspects of systematics and biogeography to understand patterns of biodiversity, and I use mammals as a study system. I aim to elucidate the factors that drive speciation at local geographic scales, as well as the large-scale events responsible for the diversification of mammals. I am interested in the application of ecological niche modeling (ENM) methods and "next-generation" sequencing technologies in biogeography and conservation biology. In addition, I am interested on taxonomic studies and inventory work on poorly studied regions. Addressing these subjects of research provides opportunities to also work on methodological and conceptual issues in systematics and biogeography—an important component of my research interests.
I am currently working on the project "Revealing the evolutionary history of the deer genus Odocoileus, with emphasis on the cariacou complex". Deer of the genus Odocoileus have never been subjected to taxonomic revision, and the status of the Neotropical populations (i.e., the cariacou complex) remains to be assessed. This study will both establish a species-level taxonomy and will provide insights about the biogeography of New World deer. Odocoileus populations in several countries of Central and South America are actively hunted, even in absence of effective management programs; therefore, by determining the taxonomic identity of populations in these regions, this study will yield essential information for conservation planning and management of species facing different degrees of extinction risks.
