Research areas

As PhD student in the Tuberculosis (TB) Vaccine group at SSI, I am working on characterizing our newest TB vaccine candidate using the mouse model. My research is centered on identifying and understanding protective immunity against Mycobacterium tuberculosis (Mtb) – both during natural Mtb infection and after vaccination. Particularly, I am studying the expression and immunogenicity of Mtb antigens during chronic TB infection, and how this affects the functionality of antigen specific T cells.

  • Vaccine mediated T cell immunity and protection
  • T cell functionality, lung migration and differentiation
  • Recognition of Mtb antigens during late chronic TB infection
  • Vaccine design and delivery
