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.
