The primary role of the position is to contribute to the RNA Platform improvements for the viral vaccine programs. The candidate will work closely with the viral vaccine director to develop and apply interdisciplinary approaches to understand the mechanisms of action of different types of RNA-based viral vaccine drug substance and lipid nanoparticle drug products. 

  • Lead the multi-step design, planning and execution of experiments to characterize the RNAs and their formulations for in vitro studies
  • Develop, establish, and execute single molecule approaches to investigate patterns of intra-cellular trafficking and localization of RNA including organelle retention of RNA and spatial RNA polarization, and their impact on translation in mammalian primary cells and established cell lines.
  • Partner with director to contribute to scientific discussions and strategic internal/external collaborations aimed at advancing the RNA Platform
  • Mentor junior scientists' research activities and provide technical guidance when necessary
