The National Research Foundation (NRF) ratings are considered the benchmark for research excellence. This year the University of the Free State (UFS) has 17 newly NRF-rated researchers. This brings the total number of NRF-rated researchers at UFS to 160.
NRF ratings are allocated based on a researcher’s recent research outputs and impact as perceived by national and international peer reviewers. The rating system encourages researchers to publish high-quality research papers in journals of high impact and to publish books through reputed academic publishers. The NRF rating system is a valuable tool for benchmarking the quality of our researchers against the best in the world.
Research at the heart of the UFS
Prof Francis Petersen, Rector and Vice-Chancellor, has indicated that the UFS provides significant support to researchers to apply for new NRF ratings or to re-apply for rating. These initiatives include the mock NRF rating panels managed by the Prestige Scholars Programme (PSP), evaluation of individual research outputs and recommendations on timely applying for rating, and improvements on rating applications by a panel consisting of internal and external members. These initiatives are bearing fruit by increasing the number of rated researchers who will transform the research profile and increase the diversity of UFS researchers.
Cultivating the best researchers.
According to Eleanor van der Westhuizen, from Research Development: “The rating of individuals is based primarily on the quality and impact of their research outputs over the past eight years, taking into consideration the evaluation made by local and international peers. It identifies researchers who count among the leaders in their fields of expertise and gives recognition to those who have a sustained production of high-quality research outputs. Several South African universities use the outcomes of the NRF evaluation and rating process to position themselves as research-intensive institutions, while others such as the UFS provide incentives for their staff members to acquire and maintain a rating.”
Cream of the crop
The UFS has also upped the ante with regard to its total number of NRF-rated researchers during the latest rating and evaluation, with an increase from 149 to 160 rated researchers in 2018.
Prof Heidi Hudson, Dean of Humanities, received an NRF B-rating, which brings the total of B-rated researchers to six. Other B-rated researchers incude Prof Johann Meyer (Mathematics), Prof Fanie Snyman and Prof Francois Tolmie (Theology), Prof Felicity Burt (Medical Microbiology) and Prof Andre Roodt (Chemistry). A total number of 10 new C-ratings and six new Y-ratings were achieved during the 2018 evaluation process.
“NRF-rating is indicative of the university’s drive to enhance its research profile nationally and internationally. Congratulations to all the scientists and scholars who received a rating in 2017. I am thankful to our academics for their commitment to the rating process,” said Prof Corli Witthuhn, Vice-Rector: Research at the UFS.

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.
Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.
The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).
According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.
In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.
“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.
H.E.S.S. has issued a complete statement about the paper published in Nature.
