For many people, retirement is a time to slow down, reflect on decades of work and perhaps tend to grandchildren. For Professor Mark Nwagwu, retirement became an opportunity to challenge himself intellectually once again and prove that the pursuit of knowledge has no expiry date.
At 89, the distinguished Nigerian scientist, poet and academic has earned a second doctoral degree, this time in Anthropology from the Institute of African Studies at the University of Ibadan, adding yet another remarkable milestone to an already illustrious career that spans more than six decades.
The feat was highlighted by former Vice Chancellor of the University of Ibadan, Professor Idowu Olayinka, who described Nwagwu’s latest accomplishment as another chapter in an extraordinary academic journey. 
Long before embarking on his newest academic adventure, Nwagwu had already established himself as one of Nigeria’s foremost scientists.
His academic journey began in 1957 at University College, Ibadan, then affiliated with the University of London. He obtained a Bachelor of Science degree in Zoology in 1961 before earning a Master’s degree in the same discipline in 1965.
That same year, he completed his first PhD in Zoology at Stockholm University in Sweden, an achievement that placed him among a select group of highly trained Nigerian scientists during the early post-independence years. Rather than resting on those accomplishments, Nwagwu continued to deepen his scientific expertise.
Between 1966 and 1969, he undertook post-doctoral research at the University of Connecticut in the United States, where he conducted studies on myosin messenger RNA and muscle protein synthesis, contributing to the growing body of knowledge in cell and molecular biology.
His academic career flourished at the University of Ibadan, where he rose through the ranks from Senior Lecturer to Reader before becoming a Professor of Zoology in 1982. As his research interests evolved, he became a leading figure in Cell and Molecular Biology and remained on the university’s faculty until his retirement in 2002.
His academic influence also extended beyond Nigeria. He served as Assistant and later Associate Professor at Brock University in Canada, further cementing his reputation as an internationally respected scholar.
But it is only one part of his story that science tells
In retirement, Professor Nwagwu ventured deeply into the humanities, publishing poetry and novels while maintaining an active intellectual life. His unique ability to bridge the worlds of science and literature has made him one of Nigeria’s most distinctive scholars.
He remains the only Nigerian to hold the rare distinction of being both a Fellow of the Nigerian Academy of Science and a Fellow of the Association of Nigerian Authors, reflecting excellence in two fields that are often seen as worlds apart.
His decision to pursue a second doctorate in Anthropology appears to embody that interdisciplinary spirit. Rather than limiting himself to laboratory science, he embraced the study of people, culture and society, demonstrating that intellectual curiosity can transcend disciplinary boundaries.
The achievement also sends a powerful message in an era when many people regard education as something to be completed in youth. By earning another PhD at 89, Nwagwu has become a living testament to lifelong learning, showing that age need not be a barrier to academic ambition or personal reinvention.
