Sarah is a PhD student at UC Berkeley. Her work focuses on the exchange of pathogens between wildlife and human populations, with an emphasis on the drivers of spillover and spillback. She applies a combination of epidemiological models, geospatial analyses, and field-based approaches to understand questions regarding the evolutionary and spatial dynamics of emerging and re-emerging zoonoses. Her current projects include modeling the risk of arbovirus spillback in Brazil, characterizing the role of spatial structure in the transmission of bat-borne pathogens in Madagascar, and applying statistical models to understand the evolution of zoonotic virulence. Before beginning at Berkeley, she graduated from Middlebury College with a B.A. in Conservation Biology, and spent two years working for the Planetary Health Alliance.
