Meet Dr. Tebogo Makhubela, a South African geologist whose journey from Soweto to international scientific recognition inspires a new generation. Awarded the 2025 National Geographic Wayfinder Award, Makhubela’s research at the Cradle of Humankind and Rising Star expedition is reshaping our understanding of human evolution and putting African science on the world stage.
A Journey From Soweto to Global Science
Dr. Tebogo Vincent Makhubela’s story is one of resilience, curiosity, and the power of education. Born and raised in Soweto, Johannesburg, he became the first in his family to pursue university studies, choosing the University of Johannesburg (UJ) for his undergraduate degree in Physical Sciences, with a focus on Geology and Chemistry. His passion for geology led him to complete his BSc Honours, MSc, and ultimately his PhD at UJ, all while overcoming the challenges of being a trailblazer in his community.
Academic Path and Professional Rise
Makhubela's academic journey reflects a relentless pursuit of knowledge. After earning his PhD in 2019, he joined UJ’s Department of Geology as an Assistant Lecturer and, through the new Generation of Academics Programme (nGAP), was promoted to Senior Lecturer by 2021. His research has focused on the geochronology and petrography of cave deposits in the Cradle of Humankind, a UNESCO World Heritage Site, as well as the study of Plio-Pleistocene low-temperature sedimentary environments and landscape evolution in Southern Africa.
Groundbreaking Contributions to Geology and Paleoanthropology
Dr. Makhubela’s work has been instrumental in advancing our understanding of human origins. He has been a key figure in the study of Homo naledi, an ancient human relative discovered in the Rising Star Cave System at the Cradle of Humankind. His research on fossil-bearing sediments has provided crucial evidence that these fossils were not deposited by flowing water, supporting the theory that Homo naledi practiced deliberate burials—potentially the oldest evidence of such behavior in the hominin record.
His expertise in geochronology—using cosmogenic radionuclides (beryllium-10 and aluminium-26), U-series, and uranium-thorium-helium dating—has helped refine the timeline of human evolution and the environmental context in which our ancestors lived.
Mentorship and Impact on African Science
Beyond his scientific achievements, Dr. Makhubela is committed to mentoring the next generation of African scientists. He actively engages in outreach and education, inspiring young people from similar backgrounds to pursue careers in science and academia. His journey from Soweto to international recognition serves as a powerful example of what is possible for African youth, especially in fields where they remain underrepresented.
The 2025 National Geographic Wayfinder Award
In 2025, Dr. Makhubela was named one of only 15 recipients worldwide of the prestigious National Geographic Wayfinder Award, an honor that recognizes exceptional leadership in science, conservation, education, and storytelling. The award not only celebrates his groundbreaking research but also his role as a global ambassador for African science.
The Wayfinder Award includes a monetary prize, access to a global network of explorers, and opportunities for further funding and leadership development. For Makhubela, it is a recognition of his perseverance and a platform to amplify the importance of African contributions to global scientific knowledge.
What This Means for Representation in Global Science
Dr. Tebogo Makhubela’s achievements are a testament to the growing influence of African scientists on the world stage. His work at the Cradle of Humankind and Rising Star expedition is not only reshaping our understanding of human evolution but also challenging stereotypes about who can lead scientific discovery. As a mentor and role model, he is helping to build a more inclusive and diverse scientific community, ensuring that African voices and perspectives are heard and valued globally.
What It Means Going Forward
Dr. Tebogo Makhubela’s journey from Soweto to international acclaim is a beacon of hope and inspiration for aspiring scientists across Africa. His story demonstrates that talent and determination can overcome barriers, and that African research is vital to solving some of the world’s greatest challenges. With the support of awards like the National Geographic Wayfinder, Makhubela is poised to continue making groundbreaking discoveries, mentoring future leaders, and ensuring that African science takes its rightful place on the global stage.
