We implement a comprehensive approach to study interactions between arboviruses (i.e. arthropod-borne viruses) and their host/vectors to identify key (a)biotic determinants of pathogenicity or vector competence. Our main goal is to better understand, anticipate and control the threat posed by these viruses. Our favorite case studies are viruses belonging to the Bunyavirales order, particularly those of the Phenuiviridae family like Rift Valley Fever virus (RVFV, responsible of a zoonotic disease and listed as a priority pathogen by WHO and WOAH) and Toscana Virus (TOSV, human pathogen), although we are also studying vector competence of West-Nile virus (WNV), dengue virus (DENV) and chikungunya virus (CHIKV).

The questions address by the team can be divided into four interconnected research axes covering key aspects of the biology of these viruses such as:

• Impact of viral genetic diversity on pathogenesis and transmission
• Interplay between the innate immune response and zoonotic Bunyavirales
• Vector competences and behaviors
• Development of innovative antivirals and vector control strategies
