We utilize a combination of fieldwork, ecological data, genomics, and bioinformatics to study how organisms evolve across both geographic and genomic landscapes.
We are fortunate to have received funding for some of the research shown below from these organizations:
Avian Population Genomics
We are studying the diversification of birds at the population, landscape, and continental levels using whole-genome sequencing methods.
- Population genomics, landscape genomics, hybrid zone genomics, and phylogeography in several avian taxa (including species in the genera: Certhia, Contopus, Leiothlypis, Setophaga, Sitta, Zosterops)
- Biodiversity genomics through time of Eastern African montane birds (currently NSF funded)

We are using multiple sequencing types, including long-read data, whole-genome resequencing Illumina data, and transcriptome data, to understand how structural variants (including indels, inversions, transposable elements, etc.) are evolving in genomes, as well as how these changes impact genome evolution, molecular evolution, population genomics processes, and diversification in multiple organisms.
- Effects of structural variants on molecular evolution and transcription variation in woodpeckers
- Population and landscape genomics of structural variants in multiple avian groups, mammals, and multiple invertebrate groups.
- Genome evolution in Blochmannia endosymbionts of carpenter ants

We were recently funded through Texas Parks and Wildlife to study Peromyscus truei comanche using conservation genomic methods. For this project, we will be assembling a high quality genome for this subspecies and resequencing multiple populations of the subspecies and closely-related subspecies to assess genomic distinctiveness, connectivity among populations, and levels of genetic diversity. This project will include morphometric analyses in concert with genomics.
More to come as we obtain and analyze data!
