Our lab employs molecular and bioinformatics tools to study the evolutionary dynamics of genes and genomes in populations and species. Some of our research projects have implications for conservation biology or medicine.  Much of our work is concerned with the evolutionary dynamics and medical effects of mutations in the vitamin K cycle genes, foremost vkorc1, in rats and mice that have developed a resistance to anticoagulant rodenticides such as warfarin.
