About the Moncrieff Lab
We are based at the Sam Noble Oklahoma Museum of Natural History on the campus of the University of Oklahoma. Our lab seeks to understand evolutionary patterns and processes in birds, with a focus on population genomics and biogeography.
​​
Our current research explores the genomic mechanisms---including recombination, selection, and structural variants---that drive early population divergence. We also investigate how geography influences gene flow and differentiation, using birds from isolated Andean ridges and around dynamic Amazonian rivers as model systems.
​​
Fieldwork is central to our approach. We conduct in-depth surveys of avian diversity, often in remote tropical regions, and prioritize firsthand knowledge of our study systems. This work includes the collection of research specimens to support genomic and morphological analyses.

Join Us
We welcome inquiries from prospective students, volunteers, and collaborators. The lab offers opportunities for undergraduate research, community involvement, and graduate training. Prospective PhD students with interests in population genomics, biogeography, systematics, and tropical fieldwork are especially encouraged to reach out (1–2 positions available beginning Fall 2026). For inquiries, email Dr. Andre Moncrieff at: moncrieff@ou.edu.

Banner photo, taken by collaborator Cameron Rutt on our recent Coari Expedition in Amazonas State, Brazil, shows a Red-headed Manakin (Ceratopipra rubrocapilla) on its display perch. The bird in this photo belongs to the only known population of its species north of the Amazon River due to a shift in this river's course thousands of years ago. June, 2025.
