  • Avian influenza viruses have the capacity to evolve genetically and to jump the species barrier to adapt to humans. These viruses have thus the potential to trigger future pandemics. The goal of the PhD project is to investigate which factors modulate influenza virus evolution and thus their ability to become more pathogenic or be more easily transmitted between individuals. More specifically, we will investigate how, within a host, a newly emerged variant interacts with its ancestor. We hypothesize that the interaction between viral variants within a host is a critical determinant of virus evolution. Therefore, developing knowledge on this subject will help prevent the emergence of new viruses of concern.

    The project will be based on the generation of viral variants by reverse- genetics and the analysis of their replication in various cell culture models and in animal models. Training will be provided for work in BSL2 and BSL3 laboratories and in various techniques (molecular biology, deep sequencing, bioinformatics).

    The PhD studentship is funded for 36 months by Région Occitanie and Agreenium and includes a monthly gross salary of 1758€. Staring date is 1/01/2022.
