My research aims to analyze the energy flow in marine invertebrates at the interface between primary producers and higher trophic levels. Copepods (Crustacea) are the main test organisms. We specifically use lipid metabolism and lipidomics to understand energy transfer but also their stress responses and adaptation to changing environmental conditions. Understanding how the natural energy flow functions can teach us a lot and can lead to applications. To get an in-depth insight into the effect of climate change on the functioning of marine species, I am also involved in the monitoring and modelling of functional responses and their impact on ecosystem functioning.
