As an Old World prehistorian, Marshall’s research focuses on two issues: early hominid lifeways, and the origins and spread of pastoralism in Africa. She has explored these topics through survey and excavation, principally in the Loita-Mara area of southwestern Kenya, and through zooarchaeological studies of faunas excavated from archaeological sites. She has also undertaken ethnoarchaeological field work designed to investigate factors that affect body part representation in archaeological sites, and alternative pathways to food production among Okiek hunter-gatherers of the western Mau Escarpment, Kenya. Marshall has been involved in a major conservation project at Laetoli, and is currently conducting zooarchaeological research on the timing of the appearance of early domestic animals in Ethiopia.
