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.

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.
