Senses are essential for survival; they help animals to orient themselves in their environments, find food, detect predators, find conspecifics and reproduce. I am interested in how animals perceive their environment, with a focus on aquatic animals and chemo-sensation. The importance of chemical communication in the aquatic environment has been over-looked; indeed, aquatic animals use chemical communication in most of their vital process. Anthropogenic disturbances, such as ocean acidification and pollution (e.g., endocrine disruptors, heavy metals, nano-plastics), may disrupt sensory driven behaviour in fish and other aquatic animals. My objective is to fully understand the pathways (at neural, cellular and whole organism levels) - from cause (sensory) to effect (physiology and behaviour), to understand the effects of such disturbances and their possible solutions. I have contributed to several scientific publication, including scientific papers and book chapters. My work was presented in several international meetings. On the last 5 years I have been involved in the training, contributing to teaching activities for undergraduate and master students in cell biology, histology and animal physiology. I was involved in the training and supervision of 18 students of different education levels.
