Throughout my research projects, I have focused on the interactions between invertebrates (molluscs, insect pests and pollinators) and biotic and abiotic stressors. For my PhD, I developed new treatments based on natural compounds (such as plant extracts and probiotics) to combat various organisms (including bacteria, microsporidia and mites) causing diseases in honeybees. I also contributed to research investigating the impact of honeybees exposure to an intestinal parasite (microsporidian) and fungicides. The aim was to better understand the role of combined stressors in pollinator decline.
Currently, I am investigating the impact of various emerging pollutants, such as microplastics and PFAS, on pollinators, including honeybees and bumble bees. The effects of these pollutants on pollinators have not yet been widely studied. More specifically, I am studying the effect of exposure to these pollutants on the immune response of these organisms.
