She and a team of researchers have worked on copper mineralization in the Central African Copperbelt of Zambia and DRC; pegmatite-hosted tin, lithium, and uranium deposits in the Damara Belt of Namibia; tin, niobium and tantalum in Younger Granites of Nigeria; lithium and gem-bearing pegmatites in Zimbabwe and Somaliland; chromitite and platinum group metals in the Bushveld Complex of South Africa and Malopo Farms Complex in Botswana; lead-zinc deposits in Ireland and Archaean gold mineralization in South Africa and Mozambique. Currently she is focusing of vanadium, PGE, uranium, lithium, and rare earth elements needed for the Green Economy.
