The Disease Modeling and Transmission section aims to investigate emerging and re-emerging viral pathogens that cause serious illness in humans. Our group focuses on vector-borne viruses spread by rodents such as Lassa virus and Hantaviruses and insects such as Crimean-Congo hemorrhagic fever virus. To investigate these viruses we develop animal models that recapitulate human disease, use these models to understand how the virus causes disease and then evaluate antivirals and vaccines that protect against disease. Additionally, in response to the COVID-19 pandemic our lab has evaluated candidate antivirals and vaccines against SARS-CoV-2. Research from our lab has resulted in multiple vaccines and antivirals against these serious human pathogens. These therapeutics are in multiple stages of pre-clinical and clinical development.
In addition to our laboratory activities, our lab has active research ongoing at field sites in Mali and Uganda where we conduct surveillance in vector and human populations to understand disease prevalence and transmission in regions where these viruses are endemic. Our efforts aim to support local public health systems and develop public health strategies that limit infection of at-risk populations.

My research focuses on understanding viral determinants of disease and evaluating vaccine candidates against pathogenic viruses. My work involves in vivo animal models and in vitro assays which are aimed at uncovering viral proteins that cause disease, these are used to inform the development of therapeutics and vaccine candidates.
