From Rural Beginnings to Breaking New Scientific Ground: The PhD Journey of Dr Nkosinathi Nxumalo
Graduation was held on Tuesday, 25 March, marking a significant milestone in the academic journey of Dr Nkosinathi Nxumalo. Growing up in the rural area of Ematholeni Reserve in Empangeni kwesakwaMthethwa, the prospect of pursuing higher education once felt like a distant dream. Financial challenges at home made the idea of attending university—let alone earning a PhD—seem nearly impossible. However, through determination, resilience, and the support of funding bodies such as NSFAS and the NRF, this dream became a reality.
Dr Nxumalo completed high school at Welabasha High School in 2010 and took a gap year in 2011. In 2012, he enrolled in a BSc in Animal Science at the University of Zululand, successfully completing the degree in 2015. His journey into research began with an NRF internship in 2016, which laid the foundation for his postgraduate studies. In 2017, he registered for an MSc in Animal Science, which he completed in 2019.
The most significant challenge in his academic career came in 2020, when he took the bold step of registering for a PhD in Animal Science (Breeding and Genetics) at Stellenbosch University. Relocating to the Western Cape was a major adjustment, made even more difficult by the onset of the COVID-19 pandemic. The uncertainty, isolation, and research delays led to moments of doubt, and at one point, he even considered returning home. However, with the unwavering support of his supervisor, Dr Molotsi, and his parents, he persevered through this challenging period.
His PhD research proved to be groundbreaking, presenting the first genome assembly of a southern African indigenous sheep breed. The study identified genes and genomic mechanisms that contribute to the adaptation of Nguni sheep (Zulu ecotype) to local environments, particularly their resilience to high temperatures and endemic diseases. Additionally, the research uncovered genetic links between the Zulu ecotype and European sheep populations, providing valuable insights into their history and evolutionary development.
As Dr Nxumalo celebrates this achievement, he reflects on a journey that was far from easy but ultimately shaped him into the researcher he is today. His story stands as a testament to the power of passion, perseverance, and the right support, proving that even the most ambitious dreams can be realised.
