Nigerian Scholar Makes History as First Black Woman to Earn Pure Mathematics PhD at UNISA

Nigerian mathematician Professor Oghenetega Ighedo made history as the first Black woman to earn a PhD in Pure Mathematics from the University of South Africa, inspiring greater participation of women in STEM fields.

Professor Oghenetega Ighedo has achieved a historic milestone by becoming the first Black woman to earn a Doctor of Philosophy (PhD) in Pure Mathematics from the University of South Africa (UNISA), marking a groundbreaking achievement in the institution’s 148-year history. The Nigerian-born academic reached this feat while serving as an Associate Professor in UNISA’s Department of Mathematical Sciences, further cementing her place among Africa’s leading scholars.

Her academic journey began in Nigeria, where she obtained a Bachelor of Science degree in Industrial Mathematics from Delta State University. She later earned a Master of Science in Pure Mathematics from the University of Ibadan before enrolling at UNISA for her doctoral studies. Despite balancing the demands of family life as a mother of three, she completed her PhD in just three years, demonstrating remarkable commitment and determination.

Ighedo’s accomplishment has been widely celebrated as an inspiration for women and young Africans pursuing careers in science, technology, engineering and mathematics (STEM). Her success highlights the growing contributions of African women to fields where they have traditionally been underrepresented, particularly advanced mathematics.

As an Associate Professor at UNISA, Ighedo has built a reputation for excellence in teaching, research and mentoring students. Her work continues to encourage greater participation in mathematics while contributing to the advancement of research in the discipline. Her achievement is also expected to motivate future generations of female mathematicians across Africa and beyond.

The recognition has attracted praise from academic institutions and public figures. The Nigerians in Diaspora Commission (NiDCOM) commended her outstanding achievement, describing it as a source of pride for Nigeria and a testament to the impact of Nigerian professionals excelling on the global stage.

Ighedo’s story stands as a powerful reminder that perseverance, dedication and academic excellence can break long-standing barriers. By becoming the first Black woman to earn a PhD in Pure Mathematics at UNISA, she has not only made history but has also created a lasting legacy that will inspire aspiring scholars, especially women, to pursue ambitious goals in mathematics and other STEM disciplines.
