UFS celebrates excellence through its research hubs
The university considers its research chairs and the possibility of future chairs as an integral and strategic initiative to increase its national and international standing through excellent academic and research leadership.

The University of the Free State (UFS) is proud of its research leaders. As of 2018 the UFS has 156 NRF-rated researchers and five Sarchi Research Chairs. These chairs are designed to attract and retain excellence in research and innovation at South African public universities.

Getting the better of vector borne and zoonotic viruses

Prof Felicity Burt leads the Vector Borne and Zoonotic Virus Research Group in the Department of Medical Microbiology and Virology at the UFS. She was awarded a Research Chair to, among others, investigate medically significant vector-borne and zoonotic viruses currently circulating - mainly viruses transmitted by mosquitos and ticks, and viruses transmitted from animals to humans. 

“Years ago, no one knew what Ebola was. One outbreak later, backed by many media reports, and it is almost a household name. The same goes for the recent Zika virus outbreak in South America,” she explains the public’s interest and fears. To prevent the spread of vector-borne viruses to new areas, surveillance and awareness is important. Here in Bloemfontein, Prof Burt and her team are establishing surveillance programmes.

Why research on fungal infections?

“Many diseases no longer pose a threat to humans and life expectancy is prolonged. However, this has also caused an increase in various opportunistic infections, and most of all, fungal infections,” says Prof Carlien Pohl-Albertyn, who is heading the Research Chair for Pathogenic Yeasts in the Department of Microbial, Biochemical and Food Biotechnology. And the rise in resistance to antifungal treatments requires research into pathobiology, including new drug and treatment options. 

Activities of the Research Chair in Pathogenic Yeasts builds on existing research strengths and will contribute towards understanding pathobiology of medically significant pathogenic yeasts belonging to the genera Candida and Cryptococcus. 

Understanding higher education for more equality and justice

Prof Melanie Walker, from the Centre for Research on Higher Education and Development (CRHED) does research on higher education, inequalities and social justice, and how, or if, universities foster the human capabilities and aspirations of students. Does higher education make a difference to the lives of students, their families and communities? 

Prof Walker says the Research Chair on Higher Education and Human Development looks at issues of access, participation and transitions into work, as well as gender, race and social class. They use both quantitative and qualitative methods and includes a strand of participatory research projects with students. Ultimately, the research must contribute to debates, policy and practices in higher education, and a scholarly knowledge base.

Reduced emissions make for a better world

Prof Hendrik Swart chairs the research project that looks into low-energy lighting, using phosphor materials for light emitting diodes (LEDs). The Research Chair on Solid State Luminescent and Advanced Materials is situated at the Department of Physics

The research mainly focuses on better light emission of phosphor powers in LEDs.  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. Over the next five years they will develop and produce 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,” he says. 

Solutions to food insecurity
 

The Department of Plant Sciences’s research project dives into disease resistance and quality in field crops. Heading this Research Chair is Prof Maryke Labuschagne who focuses on crop quality breeding and disease resistance in field crops. 

Her, and her students’ research focuses on the genetic improvement of food security crops in Africa, including such staples as maize and cassava. “These crops are genetically improved for yield, drought tolerance, disease, and insect resistance, as well nutritional value,” she says. Her disease resistance research will focus on crop protein quantity and quality as well as iron, zinc, and beta-carotene biofortification of staple crops such as wheat, maize and cassava. The disease resistance-breeding project will be a continuation of the internationally acclaimed wheat rust research. 

The university considers the research chairs and the possibility of future chairs as an integral and strategic initiative to increase its national and international standing through excellent academic and research leadership.

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
