Professor Oghenetega Ighedo has reached a remarkable academic milestone after earning a PhD in Pure Mathematics from the University of South Africa (UNISA). The Nigerian-born scholar is thefirst Black womanto receive the qualification in the university’s 148-year history.

Her achievement stands out for another reason. Ighedo completed her doctorate in just three years while working as an associate professor and raising a growing family. Her journey is inspiring more young women to pursue careers in mathematics and other STEM fields.

Ighedo currently serves as an Associate Professor in UNISA’s Department of Mathematical Sciences. While continuing her academic career, she completed one of the university’s mostdemanding doctoral programswithin the prescribed three-year period.

The accomplishment marks an important moment for UNISA and the broader mathematics community. It also highlights the increasing contributions of Black women to research and higher education.

Her success is especially meaningful because Pure Mathematics has long lacked diversity. Ighedo hopes her journey will encourage more women, particularly Black women, to enter the field with confidence.

Ighedo’s love for mathematics began at home.She credits her mother, a retired mathematics teacher, for sparking her interest in the subject from an early age.

“I was inspired by my mother. I saw the way she taught mathematics, and as I grew older, I found it interesting and wanted to do it like her.”

That early inspiration shaped a lifelong academic journey. She earned a Bachelor of Science in Industrial Mathematics from Delta State University before completing a Master of Science in Pure Mathematics at the University of Ibadan.

She later enrolled at UNISA to pursue her doctorate, building on years of dedication to mathematical research and education.

Ighedo’s academic success came alongside significant personal responsibilities. She began her PhD while married, caring for two children, and expecting a third.

Despite balancing family life, teaching responsibilities, and research, she completed the program within three years. That achievement demonstrates exceptional discipline, planning, and perseverance.

Her story challenges the belief that women must choose between family and ambitious career goals. Instead, it shows that determination and strong support can help overcome demanding circumstances.

Ighedo said one reason she pursued Pure Mathematics was the lack of representation within the discipline. She wanted to help change that reality for future generations.

“My decision to study pure mathematics was motivated by the fact that not only are there few Black pure mathematicians, but there are even fewer Black women in the field.”

She now encourages young women to stay focused on their goals, even when the journey feels difficult. According to Ighedo, resilience and determination can open doors that onceseemed out of reach.

Her achievement is being celebrated as an important step toward greater representation of Black women in mathematics, science, technology, engineering, and other STEM careers.

Ighedo’s success reaches far beyond one degree. It represents progress for African scholars, women in higher education, and students who dream of careers in mathematics.

As more Black women enter STEM disciplines, achievements like hers help expand opportunities and challenge long-standing barriers. They also provide visible role models for young girls considering careers in science and mathematics.

By earning UNISA’s first Pure Mathematics PhD awarded to a Black woman, Oghenetega Ighedo has added an inspiring chapter to the university’s history. More importantly, she has shown that talent, perseverance, and purpose can create lasting change for generations to come.
