She was the first woman in Africa to obtain a Doctor of Philosophy (PhD) in experimental physics of highly correlated matter when she graduated at University of Johannesburg on 23 September 2014.

She started her PhD in the same direction, however, she switched the topic of her doctorate to highly correlated matter in experimental physics in 2007.

[1] South African Nuclear Energy Corporation (NECSA) employed her as a scientist in the Radiation Utilisation Division between 2005 and 2007.

[5] Buyisiwe made news headlines as the first woman in Africa to earn a PhD in her field in October 2014.

Research into quantum critical phenomena is not only conducive to a study of new physics in its own right, but is expected to lead to a much broader understanding of the complex yet fundamental behavior of elementary particles in metals and the cooperative phenomena in them that lead to the wide variety of useful applications of intermetallics in everyday life.
