Research Interests

My research investigates how geographical, environmental, and ecological factors shift avian distributions over time and influence diversification. To understand the geography of avian diversification, I infer evolutionary relationships and population history of bird species/populations with genomic data to test predictions from geological models, ecological niche modeling, and phenotypic assessments in comparative frameworks. I work at multiple scales, from higher-level projects on major bird radiations to fine-scale studies of closely related species/populations. My research projects are specimen-based, utilizing new material collected during field expeditions supplemented with historical material collected by previous generations of museum biologists.
