Research Focus

I am interested in the phenotypic plasticity of cod under different environmental influences - in particular the effects of ocean warming, ocean acidification and hypoxia on erythrocytes. I am particularly intrigued by the changes at the cellular level and how these affect the entire organism and the performance of the fish. In order to understand these relationships, I use a wide range of methods - from molecular biological and microscopic procedures to biochemical analyses - and combine these with physiological measurements of metabolic rate and performance under defined stress tests.
