My research focuses on the ecology of organisms in the face of global change and anthropogenic forcing. I have so far been interested in revealing how variations and adaptations at the individual or species levels can translate into changes in species interactions, food webs, community structure and functioning, and ecosystem organization. I had the opportunity to address different types of species interactions (host-parasites, prey-predators, hosts-symbionts, plants-viruses) and to study the different types of environmental pressures that are involved in the regulation of these interactions (temperature, photoperiod, food resources, landscape, etc.). I focus on the effect of climate change and land use change through an integrative approach at various ecological and spatio-temporal scales. Indeed, the erosion of biodiversity associated with global change is endangering ecosystem functions and associated services, making the study of major ecological patterns and underlying mechanisms more necessary than ever.
