Investigación

En mi grupo estudiamos los procesos evolutivos que generan y mantienen la biodiversidad. Utilizamos datos fenotípicos, genéticos y genómicos para explorar patrones de variación geográfica a varias escalas espaciales y revelar patrones de flujo génico entre poblaciones, reconstruir las relaciones filogenéticas entre linajes, e inferir los factores históricos y selectivos que generan divergencia poblacional y la formación de nuevas especies. También exploramos la base genética de los caracteres importantes en el proceso de especiación a través de la genómica comparada y utilizamos genomas completos para identificar regiones bajo selección natural y encontrar genes candidatos asociados. Estudiamos principalmente especies de aves de zonas tropicales o subtropicales, con énfasis en radiaciones recientes tanto en islas como en continentes. Otras áreas de interés incluyen biogeografía de islas, ecomorfología, bioacústica, sistemática y conservación.

 

In my group we study the evolutionary processes that generate and maintain biodivesity. We use phenotypic, genetic and genomic data to explore geographic patterns of variation at various spatial scales to infer patterns of gene flow among populations, reconstruct phylogenetic relationships among evolutionary lineages, and identify the selective and historical factors that drive population divergence and the formation of new species. We also explore the genetic basis of fitness traits important in the process of speciation through comparative genomics, using whole genomes of our target species to identify regions under natural selection and find associated candidate genes. We study mainly avian species in tropical and subtropical regions, with an emphasis on recent radiation on islands and continents. Other areas of interest include island biogeography, ecomorphology, bioacoustics, systematics and conservation biology.
