Ms Xolisile Miya, who graduated with a Master of Science degree in Biological Sciences, conducted pioneering research that used molecular tools to enhance marine biodiversity monitoring in South Africa.

Supervised by Dr Angus Macdonald, her research, titled: ‘Characterising Fish Species Diversity in the uThukela MPA Using Environmental DNA Metabarcoding’, explored how genetic material left behind by marine species – known as environmental DNA (eDNA) – can be used to detect and monitor fish populations in the uThukela Marine Protected Area (MPA). This innovative approach enables scientists to assess biodiversity without having to observe or capture the animals physically.

“By analysing traces of DNA that fish leave in the water, we can identify which species are present and how they are distributed across different reef habitats,” explained Miya. “This is a powerful, non-invasive tool that helps us track biodiversity changes over time and informs conservation decisions.”

Her decision to pursue an MSc at UKZN was influenced by both academic opportunity and personal growth. “UKZN has always provided a supportive academic space that allowed me to advance swiftly, even during challenging times,” said Miya. “My passion for conservation and molecular biology aligned well with the research opportunities here, particularly the chance to work with eDNA for biodiversity monitoring.”

During her undergraduate studies in Marine Biology, Miya’s love for the ocean deepened, alongside a growing interest in molecular science. This dual fascination led her to a research area that bridges conservation with advanced genetic techniques. “I’ve always known I wanted to be a scientist,” she shared. “This research gave me the chance to combine my passion for the ocean with cutting-edge tools to address real environmental challenges.”

Miya’s work is more than academic, having real-world implications for conservation policy and management. “The data generated through my research can support more effective marine protected area management,” she said. “Using eDNA offers a faster, less disruptive and more comprehensive way to monitor fish populations, which is crucial for local and national biodiversity frameworks.”

Looking ahead, Miya is eager to further blend science and technology. “The global workforce is shifting toward digital and tech-driven economies. I plan to build on my research experience by advancing my skills in Artificial Intelligence (AI) and machine learning,” she said. “I’m especially interested in how these tools can be applied ethically in biodiversity monitoring to improve conservation outcomes without compromising scientific integrity.”

In her spare time, Miya continues to feed her intellectual curiosity by studying the potential applications of AI and machine learning in environmental science. “I want to be well-positioned for success in research during this AI revolution,” she noted.

Miya was grateful for the support system that helped her reach this milestone. “My supervisor, Dr Angus Macdonald, has been an incredible support and believed in me from the very beginning. My family and friends have been cheering me on every step of the way.

“Finally, I would like to say that Jesus is the centre of my life. As the Bible says in Luke 18.27: ‘What is impossible with man is possible with God’.”
