Evolution and conservation of fishes
Freshwater fishes represent a spectacular adaptive radiation; about 40% of all fishes (which constitute more than 50% of all vertebrates) are found in freshwater habitats which comprise only 0.8% of the Earth's surface area! My research focuses on understanding patterns of genetic variation within and between natural populations of fishes, the processes that promote and organize such variation, and their relevance to the origins and conservation of biodiversity. In particular, I am interested in population structure and the historical and contemporary processes that influence population structure, speciation and hybridization (both ecological and genetic mechanisms of divergence and persistance in the face of gene flow), and the implications of these processes to biodiversity conservation. We develop and apply techniques in molecular biology to address questions in the evolution and ecology of natural populations. Molecular genetic (utilizing mitochondrial and microsatellite DNA markers, mtDNA and intron sequencing and RFLP analyses), morphological, and ecological, studies are conducted in the general fields of population genetics, molecular ecology and systematics, and conservation genetics and biodiversity. I am also the Director of the Beaty Biodiversity Museum (BBM), the curator of the Fish Collection at the BBM and a member of Biodiversity Research Centre at UBC. I also teach undergraduate courses in Honour's Research (Biology 447) and Diversity and Evolution of Fishes (Biology 465). Please note that I will be on sabbatical in 2014-2015 and these courses will be taught by other faculty.

Graduate position openings
I currently have some openings for graduate student positions
1. Physiological constraints to hybridization in trout (Autumn 2015). This would be an MSc or PhD position investigating the role of physiological performance in westslope cutthroat trout, rainbow trout, and their hybrids in influencing spatial variation in hybridization. The project would involve both field and laboratory studies of metabolic physiology with potential to explore the genomic architecture of such variation and with implications for recovery planning.
