My research interests center on the materiality of cattle-based pastoralism in eastern Africa, and the ways that ceramic technologies, for example, have been a critical part of mobile pastoralist repertoires through time and space. My doctoral research was an ethnoarchaeological study of material culture in Samburu herding communities in northern Kenya, and I am now focusing attention on expanding our archaeological understanding of the Pastoral Neolithic period in eastern Africa. I currently co-direct two major field projects, one examining the social significance of monumental “pillar sites” built by the region’s earliest herders in the Turkana Basin, northwestern Kenya, and one examining the largest Pastoral Neolithic settlement site in eastern Africa farther south at Luxmanda, Tanzania. Upcoming plans include expanding the scope of these projects to include new excavations at the Jarigole Pillar Site, a megalithic pillar site on the eastern side of Lake Turkana, and continuing excavations and survey efforts at Luxmanda. I also maintain an ongoing commitment to ethnographic research in Samburu, and all projects are geared with an eye towards improving our understanding of pastoralist adaptations and resilience in Africa’s dryland environments.
