Meet the Member: Keneilwe Mosupye – Studying The Past, Saving The Future

For Senior Technician Keneilwe Mosupye, working at the SANBI Wildlife Biobank is a bit like being part scientist, part archivist and part detective – using animal samples collected years ago to answer questions no one has asked before 

“Biobanks preserve more than just samples,” she notes. “They preserve information, history, and potential. What makes them especially valuable is that they allow scientists to go back in time, using samples collected years ago to answer questions we didn’t even know to ask back then. Each and every sample stored properly can be used for future research, whether it’s understanding biodiversity, tracking changes in ecosystems, or even supporting forensic investigations in wildlife crime.” 

For conservationist Keneilwe Mosupye, her work as SANBI Wildlife Biobank Senior Technician is a bit like being part scientist, part archivist and part detective. 

That’s especially true at the SANBI Wildlife Biobank, which holds samples from species all over the world – including some of the rarest, most endangered animals around. 

Currently, the biobank collection, housed at the National Zoological Gardens in Pretoria, consists of more than 190 000 different samples from approximately 70 000 individual animals, representing over 880 species from 204 families, collected from 44 countries.

It’s a big job – and a long way away from where she started.

“I like to think of my background as a small journey map,” she laughs. “I was born in a small village in Moretele Municipality within the Bojanala District in North West. I currently live in Pretoria, where life keeps me busy and growing. I studied at North West University, where I explored Zoology, learned a lot, and probably consumed disgusting amounts of Coca Cola. I come from a small family with one younger sibling, which definitely shaped who I am today.”

But the learning never stops. As science advances, biobanks need to continuously adapt their processes, infrastructure, and skills to remain relevant and useful. Keeping pace with the evolving needs of research, conservation, and technology means a lot of work

SANBI Wildlife Biobank Senior Technician Keneilwe Mosupye attended Barcode of Wildlife voucher specimen training to learn how to combat the illegal wildlife trade.

Fortunately, one of the highlights of her job has been the opportunity to continuously learn and develop new skills – an opportunity that Keneilwe has embraced wholeheartedly, attending training and national and international conferences wherever she can. 

“I’ve been exposed to different aspects of biobanking, from sample management and documentation to quality processes and specialized training such as chain-of-custody sampling. These experiences have helped me understand how every step in the biobanking process contributes to the bigger picture of conservation and scientific research.”

We caught up with Keneilwe to hear more about her biobanking experiences.

What’s a typical work day like for you?
A typical day in my role is a balance between science and structure. I work with biological samples (receiving, processing, and storing) while making sure all the documentation is accurate and up to standard. There’s also a lot of coordination behind the scenes, from permits to data management. Some days feel like lab work, others feel like admin, and occasionally it feels like I’m part investigator, making sure everything checks out.

What makes biobanks so important?
To me, it’s a bit like creating a time capsule for biodiversity. Every sample has a story to tell, and by preserving it properly, we’re making sure that story can continue to contribute to science, conservation, and even wildlife protection long into the future. It’s rewarding to know that the work we do today may help answer important questions years from now.  In a field where species are constantly under threat, biobanks have become a safety net, making sure that critical biological material isn’t lost and can continue to contribute to science and conservation long into the future.

What inspired you to pursue this career? And what keeps you motivated?
I think it started with a mix of curiosity and a soft spot for wildlife. I didn’t realize at first that I’d end up enjoying the structured, detail-oriented side of conservation as much as I do, but here we are. Knowing that the work isn’t just a routine but has purpose, has kept me motivated.  In a field where species are constantly under threat, biobanks have become a safety net, making sure that critical biological material isn’t lost and can continue to contribute to science and conservation long into the future.

What’s the best part of your job?
What I’ve enjoyed most is knowing that the work we do today can support important discoveries and conservation efforts in the future. It’s a role that has challenged me to grow professionally while allowing me to contribute to something meaningful. I’ve also gained a much deeper appreciation for the role biobanks play in supporting research, conservation, and biodiversity management. Working with biological collections has taught me the importance of accuracy, traceability, and preserving samples to the highest standards.

What issues/challenges do you think the BBSA faces?
One of the biggest challenges I think the BBSA faces is that much of the work happens behind the scenes, so people don’t always realise the value and impact of biobanking. There’s also the ongoing challenge of managing growing collections while ensuring that samples, data, and documentation remain accurate, accessible, and well-maintained. I think we can address these challenges by continuing to invest in collaboration, training, and awareness. 

What’s one interesting thing you’ve learned while working at the biobank?
One of the biggest lessons for me has been that the smallest details matter. Something as simple as accurate documentation or proper sample handling can determine whether a sample remains useful for research years down the line. It gave me a whole new appreciation for the work that happens behind the scenes.

What do you do to relax?
I’m quite adventurous, so I love exploring new places, trying new experiences, and stepping outside my comfort zone. A random weekend could find me anywhere from trying a new restaurant, experimenting in the kitchen, exploring a new spot, or chasing a new experience. I’m someone who believes life is about staying curious, having fun, and creating memories along the way.

What are your dreams? Where do you see yourself in ten years?
My dream is to make a meaningful contribution to biodiversity conservation in South Africa and beyond. In ten years, I hope to be leading projects that bridge science, conservation, and innovation, while mentoring young professionals entering the field. I’d like to look back knowing that I’ve helped protect our natural heritage – and inspired others to do the same.
