We utilize a combination of fieldwork, ecological data, genomics, and bioinformatics to study how organisms evolve across both geographic and genomic landscapes. Our research focuses on evolutionary, biodiversity, and landscape genomics.

Evolutionary Genomics

Our goal is to better understand how and why species’ genomes change through evolutionary time. We are using genome, methylome, and transcriptome data to look at evolutionary genomics questions, and largely focus on birds because of the plethora of data available about their natural histories, as well as ever-expanding genomic resources.

Current Projects:

Transposable element evolution in several groups of birds (mostly woodpeckers).

Population genomics of diversification in several North American bird species (treecreepers, nuthatches, others).

Biodiversity and Landscape Genomics in Sky Islands

We are studying patterns of diversification in high-elevation species at various spatial and temporal scales in two sky island systems: the Ethiopian Highlands and the Madrean Sky Islands of the southwestern USA and northwestern Mexico. Our goal with these projects is to understand how fragmented habitats (natural or human-caused) impact evolution of natural populations.

Current Projects:

Hierarchical landscape genomics of sky island species and their symbionts in the Madrean sky islands.

Biodiversity genomics and landscape genomics of birds in the Ethiopian highlands.

Ant and microbe co-evolution (genus Camponotus) across the fragmented forests of Western United States mountain ranges
