Jeremiah Hlahla: Overcoming adversity to achieve a PhD in Botany

14 April 2025 | Story Martinette Brits | Photo Kaleidoscope Studios

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.”

UFS involved in project to light up the townships

2006-06-06

The parties involved with the project are from the left: Prof Hendrik Swart (Departmental Chairperson of the UFS Department of Physics), Dr Thembela Hillie (CSIR), Prof Neerich Revaprasadu (Department of Chemistry at the University of Zululand) and Dr Wynand Steyn (CSIR).

UFS involved in project that could light up the townships

The University of the Free State’s (UFS) Department of Physics is involved with a project that could make life easier in the townships through the use of artificial light.

“The project is based on the use of sunlight to activate nano material in for example cement and paint during the day. At night the cement or paint can then radiate light,” said Prof Hendrik Swart, Departmental Chairperson of the UFS Department of Physics.

According to Prof Swart an amount of R3,9 million has been made available by the Council for Scientific and Industrial Research (CSIR) for the further development of the project.

Prof Swart visited the University of Florida in America in 1995 for a year where he researched luminescent phosphor material that is suitable for flat panel television screens. The red, green and blue spots on the television screens originate from these kinds of phosphor materials. “At that stage plasma television screens were only a dream. Today it is sold everywhere,” said Prof Swart.

“Upon my return I started a research group at the UFS which investigated the degrading of phosphor material. We also started to concentrate on the effectiveness of nano phosphors. In the mean time our cooperation with the Americans was strengthened with follow-up visits to America of my colleagues, Prof Koos Terblans and Mr Martin Ntwaeaborwa,” said Prof Swart.

“Nano phosphors are basically luminescent powders that consist of particles that are 1 millionth of a millimetre. These particles can provide light as soon as they are illuminated with, for instance, sunlight. The amount of time these particles can provide light, is determined by the impurities in the material,” said Prof Swart.

According to Prof Swart nano particles are developed and linked to infrastructure materials in order for these materials to be excited during the day by sunlight and then it emits light during night time.

“The nano material is of such a nature that it can be mixed with materials, such as paint or cement. The yellow lines of roads can for example emit light in a natural way during night time,” said Prof Swart.

About a year ago Prof Swart and Dr Thembela Hillie, a former Ph D-student of the UFS Department of Physics, had discussions with Prof Neerich Revaprasadu from the University of Zululand and the CSIR about the possibility of mixing these nano phosphor particles with other materials that can be used as light sources in the building of roads and houses.

“Prof Revaprasadu is also actively involved in the research of nano materials. Our efforts resulted in the CSIR approving the further extension of the project,” said Prof Swart.

“The UFS and the University of Zululand are currently busy investigating ways to extend the light emitting time,” said Prof Swart.

“There are eight M Sc and Ph D-students from the UFS and about five students from the University of Zululand working on this research project. The Department of Physics at the Qwaqwa Campus of the UFS, with Francis Dejene as subject head, is also involved with the project,” said Prof Swart.

According to Prof Swart the further applications of nano materials are unlimited. “Children whose parents cannot afford electricity can for instance leave any object such as a lamp, that is covered with these phosphor particles, in the sun during the day and use it at night as a light for study purposes,” said Prof Swart.

According to Prof Swart the further extension of the project will take about two years. “During this time we want to determine how the effectiveness of the phosphors can be increased. Discussions with the government and other role players for the possible implementation of the project are also part of our planning,” said Prof Swart.
