20% Structure-based and machine-learning immunogen design for protein subunit and mRNA vaccines based on viral surface glycoproteins (construct design, recombinant expression in mammalian cells, purification, and stability assays), 20% Characterize protein antigenicity (binding assays using ELISAs, SPR and biolayer interferometry to evaluate binding kinetics and affinity of antibodies or designed proteins), 15% Perform structural studies (high-throughput cryo-electron microscopy of subunit vaccines as well as of complexes between viral glycoproteins and monoclonal and polyclonal antibodies as well as X-ray crystallography), 10% Design and execution of virology assays, 10% Analysis of the data to help determining the research strategy, 10% Lead projects and/or major project tasks, 10% Interactions with collaborators within our network and writing of manuscripts for publication. Master's Degree in Biochemistry or related field and four years 4 years of experience in related field like: Cryo-electron microscopy, virology assays (pseudotyped virus generation, cellular entry and neutralization assays), protein expression in mammalian cells and purification.
