The Department of Genetics at Stellenbosch University proudly welcomes Prof. Clint Rhode as its new Chair. A distinguished researcher and academic leader, Prof. Rhode brings a wealth of expertise in genetics, making his appointment a significant milestone for the department as it continues its 100-year legacy of research and education excellence.

With a PhD in Genetics, Professional Natural Scientist registration (SACNASP Reg. No. 400139/15), and as President of the South African Genetics Society (SAGS), Prof. Rhode has established himself as a leading figure in the field. His research focuses primarily on animal genetics, with a specialisation in population and quantitative genetics, disciplines that are critical for advancing breeding programmes and understanding complex genetic traits.

A Passion for Science and Leadership

Reflecting on his journey into genetics, Prof. Rhode shared how his early curiosity and love for science shaped his career path.

“I was always curious, always asking ‘why.’ Initially, I wanted to be a veterinarian but soon realised that I needed a career that allowed for constant discovery. Genetics fascinated me because it combines mathematics and biology—two things I truly enjoy. That’s how I found my way into the field.“

Despite his casual recounting of this journey, behind his words lies an exceptional academic record; having earned cum laude for all his degrees. His humility stands out as a defining trait, despite his remarkable achievements. When asked about his vision for the department, he speaks with certainty and purpose. His primary focus is on strengthening the department’s academic community and research excellence, particularly in the wake of post-pandemic challenges.

“One of my key goals is to foster an environment where researchers and students feel connected, inspired, and part of something greater than themselves.”

Stellenbosch University’s Department of Genetics is one of only two independent genetics departments in South Africa, allowing students to obtain postgraduate degrees in genetics as a standalone discipline. While many universities have merged genetics with biochemistry or microbiology, Stellenbosch remains committed to training specialists in genetics rather than general biologists; a responsibility that Prof. Rhode is passionate about maintaining.

Opportunities and Challenges in a Changing Field

Prof. Rhode describes the department’s opportunities and challenges as a “double-edged sword.” While adapting to change is necessary, it also presents a unique opportunity to rethink how the department operates and stays at the forefront of scientific advancements.

“Change management is always a challenge, but it also allows us to reassess our direction and remain relevant in a rapidly evolving field. The key will be ensuring that everyone understands the importance of these changes and how they contribute to our long-term success.“

His commitment to innovation is evident, ensuring that the department continues to be a leader in genetics research, education, and industry collaboration.

Groundbreaking Research in Genetics

Prof. Rhode’s contributions to genetics extend beyond the lecture hall. One of his most significant research projects was sequencing the first and only genome of South African abalone (perlemoen, as it is locally known), a species that plays a crucial role in aquaculture and marine conservation.

“By understanding the abalone’s genetic makeup, we can find ways to help them grow faster, protect their populations, and ensure they can survive as ocean conditions change due to climate shifts.”

Additionally, his research on the black soldier fly, a species with major applications in sustainable animal feed and waste reduction, has gained international recognition. His work explores how genetics influences large-scale breeding programmes, enhancing food production in an efficient and environmentally sustainable way.

A testament to his growing influence in the field, Prof. Rhode was recently invited as a keynote speaker at the Insect Genetic IMProvement, IMPlementation, and IMPact (Insect-IMP) workshop in Athens, Greece. Delivering a plenary session on “Population and Functional Genomics of Black Soldier Fly Mass Rearing,” he not only showcased his expertise, but also represented Stellenbosch University and Sub-Saharan Africa on the global stage. This prestigious invitation reaffirmed his standing as a leader in applied genetics, further highlighting the department’s role in pioneering research that addresses real-world challenges in food security and sustainable agriculture.

Empowering Learners, Students, and the Next Generation of Scientists

Beyond research, mentorship and student engagement remain central to Prof. Rhode’s academic philosophy. He firmly believes that students are the department’s ambassadors, shaping its reputation and impact.

“Our role as academics isn’t just to teach; we need to inspire. Students go out into the world as our ambassadors, proving why genetics at Stellenbosch University is world-class.”

For young learners considering a career in genetics, he highlights the increasing importance of computational skills and adaptability in today’s fast-changing scientific landscape.

“Genetics is evolving rapidly. If you enjoy biology but also have an interest in statistics, AI, and computing, this field is for you. It’s where the future of medicine, agriculture, and biotechnology is being shaped.”

Beyond the Lab

Outside of academia, Prof. Rhode has a creative side that may come as a surprise. He is an avid cook and amateur mixologist, treating the kitchen as his personal lab. Known for his signature chocolate brownies, lamingtons, banana muffins, and cinnamon rolls, which, according to him, are better than Cinnabon’s, he laughs as he shares how his passion for cooking ties back to his love for science.

“I don’t get much time to do experiments in the lab these days, so I experiment in the kitchen instead!”

Despite his demanding role, he values solitude and reflection, setting aside Sundays as his ‘Day of Solitude’ for personal growth and relaxation. When asked what most people don’t know about him, Prof. Rhode shared an unexpected answer: he considers himself an introvert at heart.

“Public speaking and leadership roles were not something that came naturally to me. I had to grow into them over time. But while I’ve learned to embrace these aspects of my career, I still cherish the quiet moments where I can just be, well… Clint.”

Looking to the Future

With the department celebrating its centenary, Prof. Rhode sees this as both a moment for reflection and a time to set ambitious goals for the future.

“It’s a time to celebrate our past achievements while also preparing for the next 100 years. How do we stay relevant? How do we keep pushing the boundaries of genetics? These are the questions that will guide our future.“

As the department embarks on this exciting new chapter, students, staff, alumni, and collaborators are invited to participate in the upcoming centenary events and engage with the department’s latest research initiatives and academic developments.

A Homegrown Leader with a Bold Vision

As your departmental scribe, I have witnessed Prof. Rhode’s journey from PhD student to Postdoctoral Fellow, Lecturer, Senior Lecturer, Professor, and now Head of Department. As a homegrown leader, he possesses an in-depth understanding of the department’s inner workings and is uniquely positioned to build on its legacy. I look forward to seeing how his vision will shape the future of genetics at Stellenbosch University.

As the year draws to a close, the familiar rhythm of academic life begins to soften. Laboratories hum quietly as annual cleanups commence, with the faint smell of ethanol lingering as surfaces are meticulously decontaminated. The Genetics Department; a hub of scientific innovation, surrounded by the brilliant purple blooms of jacaranda trees—finds itself in a moment of reflection. 2024 has been a challenging year, yet as the staff gathered for their final academic meeting, the air was thick with the sense of reward that comes from perseverance.

After discussing strategic plans for 2025, finalizing grant reports, and providing postgraduate students with feedback on their theses in preparation for March graduations, it was time to embrace an annual tradition: the year-end lunch at Le Pommier Wine Estate. Seated outdoors under the dappled shade of umbrellas, a light summer breeze carried the scent of oak barrels and blooming flowers, setting the perfect tone for the afternoon. The lively chatter at the long, communal table reflected the camaraderie that binds the department. Glasses of Le Pommier’s house wine clinked in celebration, not only of the year’s accomplishments but also of the relationships and shared experiences. Conversations flowed effortlessly, from tales of international conferences and innovative teaching methodologies to the joys of family life and cherished pets. Even amidst the intensity of academia, it was a reminder that at its core are people—passionate, curious, and deeply human.

The Head of Department (HOD) Mr Willem Botes, rose to deliver a heartfelt speech. With a mix of pride and poignancy, he recounted the department’s achievements over the year and highlighted that the success of any academic department is rooted in teamwork. He extended heartfelt gratitude to Thanja Alison and Morney Engelbrecht, whose dedication as the department’s management and secretary ensured the smooth functioning of operations throughout the year. Their contributions were met with warm appreciation from all present.

Mr. Willem Botes then re-introduced the incoming HOD, Prof. Clint Rhode, a moment met with cheers and applause as staff eagerly welcomed the promise of fresh ideas and visionary leadership. Yet, the mood turned wistful as he paid tribute to Prof. Louise Warnich, who, after decades of groundbreaking research and steadfast leadership, was bidding farewell upon her retirement.  Professor Warnich’s farewell speech was inspiring. She reflected on the early days of her career when genetic experiments were painstakingly slow—DNA plasmid isolations that took five days, compared to today’s hours-long processes. Her journey, from lecturing Genetics 344 to becoming a professor, HOD, and ultimately Dean of Science, left us all in awe. As she spoke, the table fell silent. Throats tightened, and a few discreetly wiped their eyes. Her legacy, both as a scientist and as a mentor, was undeniable. “It’s been an honor,” she concluded, her voice steady but her emotion evident, “to watch this department grow and flourish.” The staff raised their glasses in a heartfelt toast—to the past, the present, and the future.

This wasn’t just a lunch; it was a celebration of resilience, an ode to the bonds of community, and a moment to honor the legacies that have shaped the department. As the staff departed, the weight of the year seemed somewhat lighter, replaced by the buoyancy of hope and gratitude.
