Brief synopsis of current research:
My area of research interest is the molecular systematics and population genetics of vertebrate species, including terrestrial, freshwater, and marine fishes and mammals. Sequence analysis of DNA amplified by PCR generates far larger character sets, and facilitates more detailed analyses of intraspecific variation and phylogenetic relationships among species than are possible with conventional genetic or morphological analyses. Well-resolved, highly-corroborated phylogenies based on macromolecules can generate and test hypotheses about morphological, biogeographic, and behavioral evolution. Current investigations include:

(1) Analysis of interspecies hybridization among North American deer (Odocoileus, Cervidae)
(2) Molecular systematics of New & Old World deer, with emphasis on Neotropical species (Cervidae)
(3) Stock assessment in the Atlantic cod (Gadus morhua), Greenland halibut (Reinhardtius hippoglossoides), and harp seal (Pagophilus groenlandicus) fisheries of the North Atlantic
(4) Evolutionary biogeography of cods and pollacks (Gadidae)
(5) Speciation and biogeography of North American pine marten Martes (Mustelidae)
(6) Behavioural evolution of true seals of the North Atlantic (Phocidae)
