Specialty

Fatty acids and lipid classes in marine food webs, climate change in temperate and polar systems, essential fatty acid nutrition, trophic ecology, lipid biomarkers, larval nutrition, larviculture and lipid enrichment of live foods. 

Research Interests

I study the mechanisms and consequences of environmental variation on energy uptake and compartmentalization in cold-water marine organisms. I am particularly interested in the effects of temperature, oxygen, oil contamination and pH on energy allocation, growth and development in early life stages of crabs and fish.  Further, I explore how these physical factors interact with climate-induced changes in food quality (total lipids and fatty acids) to influence animal survival.  I aim to provide environmentally-dependent physiological rates (i.e. growth rates, mortality rates, and tissue-specific lipid storage rates) that can be parameterized and modelled to make predictions about population persistence, biogeography and health of marine species.
