Dr Viloshanie Reddy’s PhD in Biological Sciences from UKZN marked the culmination of a journey that blended cutting-edge research with personal dedication.

Supervised by Dr Shakira Shaik and Dr Dalia Varghese, Reddy’s thesis: ‘Establishment of Micropropagation and Cryopreservation Protocols for the Critically Endangered Medicinal Plant, Siphonochilus aethiopicus (Schweinf.) B.L. Burtt,’ addresses urgent biodiversity concerns through developing sustainable conservation strategies for one of South Africa’s most endangered medicinal plants – African wild ginger.

“UKZN possesses a unique and exceptional expertise in conservation plant biotechnologies, a field that deeply interested me from the beginning of my research career,” said Reddy. “Having completed my undergraduate studies at the then University of Natal (now UKZN), the Institution has always felt like a home to me. It’s where I first discovered my passion and the dream of earning my PhD, making it the perfect place to complete my academic journey.”

African wild ginger (Siphonochilus aethiopicus) is a critically endangered species widely used in traditional medicine. Overexploitation has severely depleted its wild populations, posing a serious threat to both biodiversity and traditional healthcare systems. Reddy developed a micropropagation protocol that significantly increased plant yield and the production of siphonochilone, which is a bioactive compound found in the roots and rhizomes of the plant. Additionally, she established a cryopreservation protocol for shoot apices, creating a long-term ex situ conservation strategy for this iconic species.

“My research focused on developing a biotechnology approach (micropropagation and cryopreservation) to conserve African ginger,” she explained. “The findings have significant implications for the long-term, sustainable use of this species in both traditional African medicine and the pharmaceutical industry.”

Her interest in plant conservation was sparked during her undergraduate studies, when Professor Paula Watt introduced her to plant biotechnology. Later, working as a research assistant to Professor Norman Pammenter and the late Professor Patricia Berjak, she was introduced to the exciting field of plant conservation biotechnologies, which became her focus.

Reddy believes the impact of her work extends beyond science. “The research holds significant socio-economic importance because it developed a method to protect a critically endangered plant species,” she said. “This plant has potential future applications in both African traditional medicine and the pharmaceutical industry, making its preservation a priority. The study’s focus on safeguarding this species ensures its continued availability for a variety of uses, which could have a positive impact on both local communities and the broader economy.”

Having completed her doctorate part-time while working full-time and raising a family, Reddy is no stranger to perseverance. She currently serves as the Chief Specialist Technician for the eThekwini Municipality’s Parks, Recreation and Culture unit. “Now that I have earned my doctorate, I am equipped with valuable STEM tools that will enable me to make a more meaningful impact,” she said. “I am hopeful that the skills and knowledge I gained will help solve pressing societal issues and ultimately change livelihoods for the better.”

Reddy acknowledged the support that sustained her through the demands of balancing research, career and family. “My parents taught me the importance of lifelong learning, a value that became the foundation of my studies. My supervisors, Dr Shakira Shaik and Dr Dalia Varghese, were a tremendous help, understanding the unique challenges of a student with a full-time job and family commitments.”

She expressed deep gratitude to her mentors: Watt, Pammenter and Berjak, and credited Dr Litzi Lombardi for helping her sharpen her academic writing. “However, my greatest inspiration came from my two daughters, Keyuri and Liruthi, who motivated me to persevere through every challenge,” she added. “My husband, Kevin, provided constant support, and my family helped me navigate the entire process.”

Despite her many roles, Reddy makes time for what matters most. “Friday evenings are our special movie nights, complete with popcorn and snacks,” she shared. “We also make sure to gather for Sunday dinners, sharing funny stories from the week. For my own self-care, I’ve made reading and practicing yoga a daily ritual.”

Reflecting on her journey, Reddy said: “Pursuing a PhD while working full-time and raising a family was an overwhelming experience at times, but I was able to overcome those challenges with the help of a strong support system. I believe in the ethos of lifelong learning and am always open to the fact that there is more to discover.”

She offered advice to future scholars: “Make time for your loved ones, friends and family, and most importantly, for yourself. Staying grounded will remind you that you have people who genuinely support you. I’ve found that maintaining humility is a core value that has a lasting impact on your overall well-being. And never be afraid to ask for help.”
