Keywords : cardiac physiology/phenotypic plasticity/calcium homeostasis/fish ecophysiology

Research topics
The aim of my research is to explore the functioning of fish heart facing environmental constraints (e.g. temperature, food quality, pollution and hypoxia). I try to understand the intraspecific plasticity of the heart and the link with cardiac and metabolic performances.
