The evolutionary history of organisms leaves traces in the genomic compositions of populations. My research takes advantage of the signatures of selection, drift, migration, and changes in effective population size, among other markers, to decode evolutionary changes in species. We exploits these differences to draw conclusions on evolutionary processes using biogeographical, phylogenetic, population and molecular genetics, and ecological tools.

Currently we are investigating the genomes of South American camelids to determine signatures of selection during the domestication process. Along with identifying the genetic basis of other economically significant markers, such as color, crimp, length, thickness, and luster of the fleece. This research leads to further understanding of the domestication process of Alpacas and Llamas, more efficient agricultural practices with these organisms, and answers questions as to how domesticates influenced early human survival in the South American Andes.

 The other side of my research takes place mostly in the Puerto Rico Bank. This area serves as a great natural laboratory for speciation as it presents an interesting geographical story, some islands have been connected to each other (possible vicariance or sympatry), as others never have (possible dispersion or allopatry). Additionally, the Puerto Rico Bank has a wide variety of ecosystems for organisms to colonize and speciate. Currently we are working on a project that involves the biogeographical and evolutionary history of dwarf geckoes (Sphaerodactylus) on the Puerto Rico Bank. These reclusive geckoes tell an interesting story of dispersion, considering the genus has managed to colonize every ecosystem available on the Bank, including various oceanic islands. Dwarf geckoes serve as a great model to study island biogeography and the divergence/speciation process.
