Gudrun De Boeck

  • Research interest:Main expertise: Toxicology and ecophysiology of marine and freshwater organisms under changing environmental conditions (due to natural and anthropogenic pressures) with a focus stress physiology, energy metabolism and ionoregulation at different levels of biological organisation: molecular, cellular and organismal. Comparative animal physiology. Techniques: Toxicological tests: bioaccumulation, biomagnification and modes of action Performance tests: Swimming capacity and behaviour, challenge tests Fuel utilisation: Respiration rates and energy stores, metabolomics Ion homeostasis: Ion and toxicant uptake mechanisms, blood electrolytes and acid-base balance Biomarkers: Oxidative stress, stress and defensive proteins (e.g. metallothionein) and enzymes Regulation: stress hormones, transcriptomics, proteomics.
