I am an evolutionary biologist studying how extrinsic (ecosystem and geophysical) processes interact with intrinsic (organismal and genomic) processes to influence the evolution of populations, species, and biological communities. I study and document avian biodiversity, across multiple scales, from genomes to biological communities, recent to deep timescales, and local to continental spatial scales. I develop empirical genomic –population genetic and phylogenomic– studies that test biogeographic and speciation theory, and draw on a range of computational and high-throughput sequencing methodologies to do so. Much of my research focuses on Amazonia, as it is the most diverse terrestrial ecosystem on the planet.
