Welcome to the Leaché Lab at the University of Washington.  We are a group of evolutionary biologists in the Department of BiologyBurke Museum who study the diversity and systematics of reptiles, amphibians, and birds. The research in our lab is focused on topics including phylogenetics and species tree inference, statistical phylogeography, species delimitation, and comparative biology.

We utilize molecular genetic data to estimate phylogenetic relationships and infer current and historical population processes. Our research is collections-based, and takes us to places including Western North America, Puerto Rico, South America, Mexico, & West Africa. We are also actively exploring creative new ways to apply genomic data into our studies, and this keeps us engaged in bioinformatics.

Active areas of research include:
African Agama Diversification  / Horned Lizard Systematics  /  Phylogenetics  /  Fence Lizard Evolution  /  West African Comparative Phylogeography
