Liz focuses on diverse health issues at the interface of humans, animals (both domestic and wild), and the environment in the U.S. and East Africa. As an epidemiologist, she integrates animal and human disease surveillance, molecular epidemiology, and spatial methods to investigate environmental change and zoonotic disease transmission. Using a One Health approach, Liz works with students, interdisciplinary researchers, and local stakeholders, linking diverse tools and perspectives to address complex health challenges. In Tanzania and Rwanda, Liz has collaborated on One Health projects ranging from studies of viral transmission from wildlife to people to community-based research on connections among livestock herd health, human nutrition, and household livelihoods of rural communities.
