Summary
- I am a physician-scientist and vaccine researcher. My research is focused on preventive interventions against influenza, RSV and emerging respiratory viruses, such as SARS-CoV-2. I conduct clinical-translational research on large-scale community-based studies of respiratory viruses, with a focus on vaccines, antivirals, and diagnostics. I am also interested in defining clinical and immune correlates of protection against respiratory viruses and describing mechanisms of maternal-fetal immunity against respiratory viruses.
