Research Interests:

I am Professor of Biology, with a cross-appointment in Population Genetics to the Faculty of Medicine. Research in my lab focuses on patterns and processes of molecular and genome evolution within and among species of vertebrate animals.

I am interested in supervising honours, MSc, and PhD students in the broad areas of:

1. Phylogeographic genomics of Fisheries & Wildlife populations, including Atlantic Cod, Wolffish, Harp Seals, and Newfoundland Caribou

2. Biogeographic evolution of cods and pollocks (Gadidae)

3. Population genomic structure of the founding human population of Newfoundland, including First Nations peoples

4. Development of a novel biotechnology, Iterative DNA sequencing microarrays for evolutionary & population genomics

My lab has taken a whole-mitochondrial-genome approach to the interrelated problems of population and systematic biology. Phylogeographic analysis of completely-resolved inter- and intraspecific gene trees, based on full-length mtDNA genomes, provides the detailed historical information and necessary statistical power to evaluate vicariance and dispersal phenomena at scales of interest to fisheries, wildlife, and population biologists.
