Education
Dr. Khanyisani Ziqubu’s academic journey began at the University of Zululand, where he earned a BSc in Biochemistry and Microbiology (2017). He continued with a BSc Honours in Biochemistry (2018), focusing on protein expression and co-expression systems in Escherichia coli. In 2020, he completed his MSc in Biochemistry, investigating the effects of isoorientin on fat browning in insulin-resistant cells. This work laid the foundation for his later focus on flavonoids and adipocyte function. His doctoral studies at North-West University, completed in 2025, delved into the brown adipocyte secretome and the role of flavonoids in regulating batokine secretion. These qualifications equipped him with advanced expertise in molecular biology, mitochondrial physiology, metabolic disease mechanisms, and analytical biochemistry. Throughout his education, Dr. Ziqubu demonstrated academic excellence, earning competitive scholarships and awards, while also gaining teaching and mentorship experience. His academic path reflects a sustained commitment to bridging molecular science with real-world health solutions.
