Dr Cias Tsotetsi, newly appointed Campus Vice-Principal: Academic and Research on the UFS Qwaqwa Campus.
The University of the Free State (UFS) is pleased to announce the appointment of Dr Cias Tsotetsi as the Campus Vice-Principal: Academic and Research on the UFS Qwaqwa Campus as from 1 January 2025.
He is currently Senior Lecturer and Assistant Dean in the Faculty of Education on the UFS Qwaqwa Campus. He holds the following qualifications: BEd(Hons), Postgraduate Diploma in Education, Magister Educationis with specialisation in Policy Studies and Governance in Education, and PhD with specialisation in Philosophy and Policy Studies in Education – all from the UFS.
Dr Tsotetsi operated in the school environment for about 24 years before joining this university in 2010. Since then, he has taught several modules in the Faculty of Education and published several co-authored research articles as well as conference papers on community engagement, teacher development, and participatory action research methodologies, among others. He is also well versed in supervising postgraduate students.
He has received awards from both the university’s Scholarship of Teaching and Learning and the Research committees for his research and academic scholastic performance. He is a member of various committees, such as the Faculty of Education Academic Advisory Board and the Committee for Title Registration and has been participating in partnerships and in NRF-funded projects with peers from universities such as the University of KwaZulu-Natal, the University of Zululand, the Durban University of Technology, and the University of Venda.
“Dr Tsotetsi has a clear understanding of the current systems and operations on the Qwaqwa Campus and is positioned to drive its development. His experience and initiatives involving staff and postgraduate students are exceptional and inspiring. We look forward to Dr Tsotetsi’s valuable contribution to the UFS Qwaqwa Campus and the institution in his new position,” says Prof Prince Ngobeni, Campus Principal of the Qwaqwa Campus.
“I feel honoured to serve the university – and the Qwaqwa Campus in particular – and look forward to working with the campus and its management to develop the research portfolio,” says Dr Tsotetsi.
Prof Tredoux turns theories regarding the formation of metals on its head

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.
