I use genomic tools, like obtaining the DNA sequences from entire genomes of many species, to study the evolution of avian systems, generally in the early stages of speciation. I use this and similar strategies to understand the evolutionary processes that generate differences among species.

I’m particularly interested in exploring how changes in genomic DNA sequences lead to differences in the general appearance (e.g., morphology or coloration) and behavior of the incredible diversity of birds. One example is finding the genes that are responsible for the different coloration patterns among male capuchino seedeaters (genus Sporophila).

A part of my work also focuses on studying the patterns of genetic differentiation among individuals and populations across landscapes, with the objective to uncover the geological and demographic processes that contribute to genetic differentiation.
