Before clinical diagnosis: how wastewater is crucial in Tuberculosis surveillance || Dr. Mtetwa
Clinics can only count the people who walk through their doors. But tuberculosis doesn’t wait for a diagnosis, and our wastewater carries signs of it long before many cases ever reach a clinic.

Different Stories. Different Paths. Different Research.
From the water in the Lagos lagoon to the code in a bacterium’s genes, the podcast ranges across the sciences. Each guest brings their own expertise, so no two episodes cover the same ground.
About the show
What you are getting into
The untold stories of African scientists doing their research in Africa, told by the people doing it.
Chronicles of African Scientists is a podcast dedicated entirely to the scientists of Africa — the researchers doing rigorous, world-class research in the motherland. Each episode is a conversation with one researcher: their story, their research, and the world they are building it in.
The podcast exists to shine the spotlight on researchers on the continent. Africa is frequently discussed as a place where problems happen. Rarely as a place where solutions are being built, by Africans, with African resources, for African realities and for the world. Chronicles of African Scientists was created to correct that. Every guest is an African researcher based in Africa. Every conversation is told in their own voice. The science speaks for itself.
This is a podcast for everyone who believes the story of science on this continent is still being written — and that the people writing it deserve an audience.
- Format
- One scientist per episode. A conversation about the person, their journey and the work they are doing.
- The guests
- Scientists working in Africa, from every field — life sciences, physical sciences, social science, engineering, arts and more. Each one is pinned on the map.
- Why it exists
- To tell the untold stories of African scientists working in Africa. Hearing the story of the people behind the research, not only the results.
- Who it is for
- Everyone interested in the research being done in Africa, and the researchers solving African problems using African resources. Students and early-career scientists navigating the challenges of doing research on the continent.

Adetunji “Teejay” Adesina, Ph.D.
Virologist · Molecular Epidemiologist
- Research

Adetunji “Teejay” Adesina is a virologist and molecular epidemiologist with over a decade of research experience across Africa, Europe, and North America. He holds a PhD in Biochemistry and Molecular Biology from Obafemi Awolowo University in Ile-Ife, Nigeria, where he also completed his BSc and MSc. His scientific work spans the molecular epidemiology of Lassa virus in endemic communities in Nigeria, virus–host interactions in HIV and related primate viruses, and the evolutionary biology of zoonotic diseases. He has spent the last decade convinced that how science is communicated is as important as the science itself.
Chronicles of African Scientists grew out of a gap that most African scientists know too well. Brilliant, rigorous, consequential science is being done across Africa every day, and most of the world never hears about it. Not because the work isn’t there, but because the stories aren’t being told. We’re here to change that. Every episode is a conversation with an African researcher based in Africa — told in their own voice and language.
This platform was built for the next generation of African scientists to see what is already being built on the continent and draw inspiration from it.
