Jeremiah Hlahla
Jeremiah Hlahla, 27, proudly graduates with a PhD in Botany.

At just 27 years old, Dr Jeremiah Hlahla has achieved a remarkable milestone: earning his PhD in Botany, conferred on Thursday 10 April. His journey is one of perseverance, academic curiosity, and the determination to rise above significant personal and financial challenges.  

 

Resilience rooted in early hardship 

Growing up in Nkomazi, Mpumalanga, Dr Hlahla’s early life was marked by profound loss. His mother passed away when he was still young, and in Grade 11, he lost his father. Left without the support of his immediate family, he was placed in an orphanage alongside his sister. Despite these immense challenges, Dr Hlahla remained focused on his education.  

“From Grade 10, I stayed behind at school to do my homework and study,” he recalls. “By Grade 12, I asked the pastor if I could use the church office to study. He allowed me, and throughout matric, I would go straight from school to the church office.” 

 

A passion for science and a decisive pivot 

Dr Hlahla’s fascination with science began in Grade 4 when he first encountered the topic of Matter and Materials. “It was a fascinating subject for me,” he says. By Grade 9, he had decided to become a scientist, though he was still unsure of the specific field. 

After matric, he negotiated with an Anglo-American bursary manager to study biology instead of electrical engineering. “I later applied for biochemistry and botany at the University of Johannesburg because I enjoyed biology - but over the years, I found plant science especially interesting.” 

The pivotal moment in his life came when he was awarded an Anglo-American scholarship. “That was a huge turning point in my life,” he says. “After matric, I didn’t know what I would do next. But after one psychometric exam and two rounds of interviews, I received the scholarship, and my life improved.” 

With renewed motivation, he continued his studies and pursued a Master's degree, despite having no financial resources at the time. “When I arrived at the University of the Free State (UFS), I had just left Pretoria with my bags and no money,” he recalls. His supervisor, Dr Makoena Moloi, recommended him for a National Research Foundation (NRF) grant to cover his expenses. He was later awarded a bursary from Carl Zeiss. 

“Dr Moloi wanted a hardworking person,” Dr Hlahla says. “She also helped me improve my academic writing.”

 

Perseverance through a pandemic 

The COVID-19 pandemic brought unexpected setbacks, derailing his MSc research. “After the lockdown, I returned to find my plants had died. I had to start from scratch,” he says. Despite this, he completed his experiments by August 2021 and submitted his MSc with distinction. 

“It is incredibly rewarding to see years of hard work culminate in a PhD,” he reflects. 

 

Looking ahead: Researching for a food-secure future 

Now a postdoctoral researcher in plant breeding, Dr Hlahla is working on developing drought-tolerant edamame cultivars – research inspired by his PhD work. 

 “What excites me the most is breeding drought-tolerant edamame cultivars based on my previous research,” he says. “I am also thrilled to be working with Prof Maryke Labuschagne and Prof Rouxlene van der Merwe.” 

Dr Hlahla’s journey has given him insight into what it takes to succeed against the odds. His message to students navigating hardship is clear: 

“Stay focused on your goals. How you respond to what happens to you will determine your future. Someone is always willing to help - so find support and use it. Hard work, willingness, and determination will take you far.”

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
