Prof Paul Oberholster, newly appointed Dean of the Faculty of Natural and Agricultural Sciences.

The University of the Free State (UFS) has appointed Prof Paul Oberholster as Dean: Faculty of Natural and Agricultural Sciences as of 1 January 2024. 

Strong networks and winner of prestigious awards for research, innovation, and leadership 

Prof Oberholster is currently the Director: Centre for Environmental Management at the UFS. He completed his undergraduate and postgraduate degrees at the UFS before obtaining a PhD in water resource management at the University of Pretoria. 

After several years in secondary education, Prof Oberholster started his scientific research career as a Senior Scientist at the Council for Scientific and Industrial Research (CSIR) in 2007. In 2017, he became a Chief Scientist (the highest scientific position at the CSIR, and senior management) managing large multidisciplinary projects on the African continent related to integrated water resource management and natural-based treatment solutions/ecological engineering. 

During his time at the CSIR, he acted as extraordinary professor and lecturer in several academic departments at different institutions, including Stellenbosch University, the University of Pretoria, and the University of the Western Cape. During the same time, he received several prestigious awards for research, innovation, and leadership. 

In 2019, Prof Oberholster joined the UFS as Director of the Centre for Environmental Management and also received the National Science and Technology Foundation (NSTF) award in the category Water Research Commission, with a focus on natural-based passive phyco-remediation and phytoremediation treatment technology. In 2022, he was elected as a member of the Academy of Science of South Africa (ASSAf) in recognition of his academic achievements in South Africa, and in 2023 he was appointed as the Managing Director of the Ecological Engineering Institute of Africa (EEIA). 

Rated among top 2% in the world in the scientific category of engineering/technology, ecological engineering and environmental engineering. 

Currently, Prof Oberholster is rated among the top 2% in the world in the scientific category of engineering/technology, ecological engineering, and environmental engineering. “Prof Oberholster has an extensive and impressive international research standing and has established extensive networks and partnerships. He can lead and manage the faculty in support of the UFS Vision 130’s ultimate intent for the coming years to be a research-led, student-centred, and regionally engaged university,” says Prof Francis Petersen, UFS Vice-Chancellor and Principal. 

“It is a privilege to be part of the leadership team in the Faculty of Natural and Agricultural Sciences – we will ensure that the faculty is known nationally and internationally as an excellent faculty serving our community. We aim to consolidate and build on the strengths of the university in order to extend its excellence in research and teaching and learning, which is imbedded in the UFS Vision 130,” says Prof Oberholster. 

Prof Oberholster will succeed the current Dean, Prof Danie Vermeulen, who will be retiring at the end of December 2023.

A research project into low-energy lighting using phosphor materials for light emitting diodes (LEDs) at the Department of Physics at the University of the Free State (UFS) has received further recognition. 

The South African Research Chairs Initiative (SARChi) has awarded further funding for the Research Chair in Solid State Luminescent and Advanced Materials situated in the department. Prof Hendrik Swart, a Senior Research Professor in the Department of Physics, says this means that the Chair will carry on receiving funds from SARChi for another five years. The Initiative also awarded Prof Swart in 2012 for the research, which resulted in funding for equipment and among others, bursaries.    

Better light emission in LED’s
The research focuses on better light emission of phosphor powers in LEDs. It is also looking into improving LED displays in flat screens. The research into solar cells has shown that phosphors can also increase their efficiency by increasing the range of light frequencies, which convert into electricity. It also entails that glow-in-the-dark coatings absorb light during the day and emit it at night. 

Prof Swart says over the next five years the research will focus on developing and producing devices that emit better light using the substances already developed. “We need to make small devices to see if they are better than those we already have.” In practical terms, it means they want a farmer’s water pump that works with solar energy to work better with less energy input.” 

Device that simulates sunlight
Prof Swart says the renewal of the Chair’s funding means the department can now get equipment to enhance its research   such as a solar simulator. The solar simulator uses white LEDs whose intensity output and wavelengths can be tuned. The output is measured in number of suns. It enables researchers to work in a laboratory with a device that simulates sunlight.     

According to Prof Swart the long-term benefit of the research will result in more environmentally friendly devices which use less energy, are brighter and give a wider viewing field. 

About 10 postdoctoral researchers are working on the studies done by the Chair in collaboration with the Council for Scientific and Industrial Research. 

The Research Chair Initiative aims to improve the research capacity at public universities to produce high-quality postgraduate students, research and innovative outputs. The criterion for evaluating the department’s Chair includes aspects such as how much development has occurred over the past five years. The assessors look at features such as the number of students the research entity has trained and how many publications the research team has produced.
