Research Interests
My research focuses on how pre-existing immunity to influenza modulates virus-host interactions in the antigen-experienced host. Specifically, I try to dissect the different aspects of both the innate and adaptive branch of the host immune response to vaccination and repeated influenza virus infections, and how these parameters contribute to long-lasting protection. Ultimately, insights gained from my research will translate in development of new and optimization of existing adjuvants and vaccine approaches against influenza.
