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.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
