Comparative Genomics

Genomes spanning the rich living and extinct diversity of species are being sequenced at an unprecedented rate. Analyses of whole genome alignments of hundreds, and eventually thousands, of species offer unparalleled power to resolve phylogenetic controversies, identify genomic innovations of adaptation, and dissect the genetic architecture of reproductive isolation.

Felid Evolution and Genomics

A major focus in the lab is developing and applying genomic resources for the cat family to connect genotype to phenotype, and reveal the evolutionary consequences of historical and contemporary hybridization between species.

Phylogenetics, Phylogeography and Conservation Genomics

We use phylogenetic approaches to understand when and how mammals diversified, and to aid in the delimitation of species and conservation units for management.
