Research activities: I specialise in the establishment of model interactions involving eukaryotic pathogens and their macro- or microalgal host(s). I lean on interdisciplinary array of tools, including biochemistry, histology, genomics to tackle questions ranging from algal ecology to the physiology and evolution of parasites in aquatic (marine and freshwater) systems, disease management and biosecurity in commercial algal cultivation. I have specific expertise in the oxidative stress, programmed cell death, and more generally the functional annotation and characterisation of the defence genes of algae. More recently, I have started transferring this expertise to disease management in commercial facilities, and to the development of biosecurity for algal aquaculture.
