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.”

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Profile of the gravitational waves of the colliding black holes.

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
