Research Interests: Birds diversity and evolution, particulary on the drivers of variation in eggs and nest across different species.

David has broad interests in the natural history, behavioral ecology, and evolutionary diversification of avian life histories. He received his BA from Universidad de Antioquia (Colombia), where he studied cooperative breeding behavior and nest predation for several bird species associated with rivers. Then, for his MS in the Universidad de los Andes (Colombia), he studied adaptive variation in eggshells across elevational gradients in the Andes. After performing extensive fieldwork in long-term research projects and being a curator in the birds and eggs collection at the Instituto Humboldt in Colombia, he joined the Stoddard Lab at Princeton University. He is exploring avian eggshell evolution, with a focus on how trait evolution influences patterns of ecological diversity.
