Biodiversity, systematic, and conservation research in our laboratory involves a variety of genetic and morphological character sets on a variety of fish groups. For example, we have focused most of our research on species of the following families:
Lampreys: Family Petromyzontidae
Phylogeny of lamprey species of the world
Species identification using molecular markers
Testing the satelite speciation model
Sturgeons: Family Acipenseridae
Species diversity in Central Asian genus Pseudoscaphirhynchus
Species differentiation in North American Scaphirhynchus
Conservation genetics of imperiled species Scaphirhynchus and
Pseudoscaphirhynchus based on mitochondrial and nuclear genes.
Shiners and Minnows: Family Cyprinidae
Phylogenetic relationships of shiner-like Cyprinids of North America
Several studies of molecular and morphological variation in Notropis,
Campostoma, Nocomis, Pteronotropis, and Hybopsis.
