My research interests are in reconstructing technologies and subsistence economies of prehistoric African people, especially during the terminal Pleistocene/Holocene period. In my PhD thesis (The Later Stone Age in the southern Cape, South Africa, during the terminal Pleistocene/early Holocene with a focus on Klipdrift Cave), I discussed the lithic technology and shellfish subsistence of the coastal people in the southern Cape, South Africa, during a period of rapidly rising sea levels, around 12 000 years B.P. I explored methods and techniques of tool making at this time and the role shellfish exploitation played in the diet of coastal dwellers plus examining theories associated with the gathering of marine molluscs. I compared and contrasted technology and shellfish composition at Klipdrift Cave with that of contemporary sites, especially Matjes River Rock Shelter and Nelson Bay Cave.

I am also interested on community participation not only in production of palaeonthropological/archaeological knowledge but also in preservation of the heritage. Along this line, I worked with a colleague (Dr. Asmeret G. Mehari) on the Oldupai local community perceptions towards paleoanthropological/archaeological researches and the findings have been published in an edited proceeding.

Currently, I am working with colleagues from within the Department of History (University of Dodoma) to investigate the people known orally by the Wagogo in Dodoma as Wambambali together with investigatin earlier technological approaches including Iron Age, Later Stone Age, and the Middle. With other colleagues (Amanuel Beyin, University of Luisville and David K. Wright, University of Oslo), we are investigating technological adaptations of the Middle Stone Age people in the Kilwa coast.
