I have recently arrived from Canada and started a PhD position with Bournemouth University and the Salmon and Trout Research Centre at GWCT as part of the SAMARCH project. Before moving to England, I lived in Iceland, where I completed my Master’s degree studying trophic interactions between rainbow trout (Oncorhynchus mykiss), sea trout (Salmo trutta), and Arctic charr (Salvelinus alpinus).

For my PhD thesis I will test the hypothesis that current declines in anadromous salmonid populations are a function of changes in their migration phenology. More specifically, I will be studying Atlantic salmon (Salmo salar) in the River Frome, and am interested in what intrinsic factors (such as the length and weight of juvenile salmon) and extrinsic factors (such as water temperature) affect the likelihood of salmon surviving to adulthood and migrating back to their natal rivers, where they lay their eggs. Atlantic salmon have a complicated life cycle, and there is still a lot to learn about their long migrations. I hope that the findings from my research will help inform management and conservation efforts for salmon in this region.
