Ighedo’s academic journey began in Nigeria, where she obtained a Bachelor of Science in Industrial Mathematics from Delta State University before earning a Master of Science in Pure Mathematics from the University of Ibadan. She later enrolled at UNISA, where she broke a long-standing barrier by becoming the first Black woman to receive a doctorate in Pure Mathematics from the institution.

Currently an Associate Professor of Pure Mathematics, Ighedo has built a distinguished academic career through her research, teaching and mentorship. Her work has contributed to advancing mathematical research while inspiring more women and young Africans to pursue careers in mathematics and related scientific disciplines.

Speaking about her achievement, Ighedo has consistently emphasised the importance of perseverance, discipline and lifelong learning, encouraging young people, particularly girls, to pursue careers in STEM despite the challenges often associated with the field.

Education stakeholders have described her accomplishment as a significant breakthrough for diversity and inclusion in higher education, noting that it demonstrates the growing impact of African scholars on global research and innovation. They also said her success serves as an inspiration to aspiring mathematicians across the continent.

The achievement comes at a time when governments, universities and development organisations across Africa are intensifying efforts to increase female participation in STEM education and research. Experts believe Ighedo’s success will encourage more young women to pursue advanced studies in mathematics and other science-related disciplines, helping to close the gender gap in academia.
