MU Africa Hub plays an essential role in accomplishing the University of Missouri’s mission and commitment to robust public service by cultivating a space where scholars and students can deconstruct stereotypes about the continent, explore the vast terrain, examine diverse cultures and traditions, and illuminate pressing issues, thus shaping new frontiers of knowledge that encourage and promote understanding and study of Africa.
