‘A Decade of Impactful Research and Internationalisation’ - an apt description of Prof Corli Witthuhn’s tenure as Vice-Rector: Research and Internationalisation.

As my second term in the position of Vice-Rector: Research and Internationalisation comes to an end, I thought it fitting to summarise a few of the highlights of the past decade. Highlights were indeed many, and it is important to note that these are just brief extracts from some notable areas.

The past ten years have been a period of exceptional development and maturation in the portfolio of research and internationalisation at the UFS. It has also been a time of immense personal and professional growth for me, and truly represents the pinnacle of my academic career. I am humbled by the many highlights that have characterised the UFS research journey over this period, and am deeply indebted to a team of innovative, dedicated, and multi-talented academic and support staff members, as well as national and international stakeholders, without whom these achievements would not have been possible.

Developing excellent researchers

Nurturing young research talent and providing appropriate research mentorship has always been a passion and aspiration in my career. I am particularly proud of the strides made over the past ten years in attracting and developing research talent at the UFS, as reflected by

• the increased diversity of UFS researchers;
• support for emerging scholars;
• the expansion of our research capacity through the appointment of talented research fellows; and
• the increased number and quality of postgraduate students and postdoctoral fellows who are drawn to the UFS.

During my term, I strongly advocated the principle that a doctoral degree should be a prerequisite for the appointment of academic staff. This has contributed to a shift in the number of academic staff holding doctoral degrees as their highest qualification – from 39,5% in 2012 to 58% in 2022. In turn, their appointment improves our capacity to supervise doctoral students.

In addition, support staff were encouraged to obtain postgraduate degrees, which facilitated access to career paths previously closed to them. Many staff members in the Directorate Research Development (DRD), the Centre for Graduate Support (CGS), the Library and Information Services (LIS), and the Office for International Affairs (OIA) have obtained master’s and even doctoral degrees.

The following development initiatives, established during my tenure, deserve special mention:

Prestige Scholars and Future Professoriate Mentoring Programmes

These two recent mentoring programmes follow a holistic development approach that includes personal, academic, and professional development strategies and interventions. The Prestige Scholars Programme has contributed to the development of NRF-rated researchers in the Y- and P-rating categories, and many of the participants have been promoted to professorial rank. This programme has been commended by external reviewers as a ‘best practice’ model for early career development in South Africa. It has directly led to fundable intellectual projects, extended international collaboration, and increased research output (e.g., the number of subsidised units rose from 566 in 2012 to 1 400 in 2021). The Prestige Scholars Programme has been invaluable in promoting the regional demographic profile of UFS staff.

The first cohort of the Future Professoriate Mentoring Programme completed the programme at the end of 2022. The individualised attention and group mentoring had a significant impact on the performance of these young academics. Twelve of the 28 participants have received NRF-ratings during the past two years. This cohort was also noteworthy for the publication of eight books with prestigious international publishers. Fifteen of the participants have been promoted to Associate Professor level and one to Full Professor at the time of writing. Five received teaching excellence awards in 2022. Two participated in the University of Michigan Presidential Scholarship Programme (UMAPS) in 2022, and four completed productive sabbaticals at international universities in America and Europe.

Staff productivity

Staff productivity has shown an encouraging upward trajectory over the past ten years, with the total number of publication units increasing from 566 in 2012 to 1 400 in 2021. The publication output units (books, conference proceedings, and journal articles) as measured by and reported to the Department of Higher Education and Training (DHET) indicates consistent growth, especially over the past five years. The UFS excelled in the publication of books. Over an eight-year period, the institution produced the most subsidy-qualifying book outputs in the South African higher education sector.

NRF Ratings

NRF rating remains an important yardstick against which to measure the standard of our research activities. Over the past ten years, we have shown consistent, and in some categories (for example in the Y-rating, which refers to researchers 40 years and younger with the potential to establish themselves within a five-year period of evaluation), exceptional growth in the number of NRF-rated researchers:

2012 2022 increase

NRF RESEARCHERS 118 214 81%
Y-RATED RESEARCHERS 9 59 555%

A central platform of our research enterprise that has been important to me, is the need to identify, develop, and assist black and female researchers to excel and establish themselves in the competitive academic environment that characterises research-led universities. The number of rated black researchers increased from 7% in 2017 to 19% in 2022, and the number of rated female researchers rose from 29% in 2017 to 35% in 2022.

Research chairs

The UFS has doubled the number of SARChI Research Chairs over the past 10 years. The UFS currently hosts six SARChI Research Chairs funded by the National Research Foundation (NRF) and the Department of Science and Innovation (DSI). Five of these have Tier 1 status and four are held by women researchers.

The UFS SARChI Research Chairs (and their holders) are:

• Solid State Luminescent and Advanced Materials (Prof Hendrik Swart)
• Higher Education and Human Development (Prof Melanie Walker)
• Disease Resistance and Quality in Crops (Prof Maryke Labuschagne)
• Vector-Borne and Zoonotic Pathogens (Prof Felicity Burt)
• Pathogenic Yeasts (Prof Carlien Pohl-Albertyn)
• Strengthening Urban Economies: People, Place, Production and Policy (Prof Ivan Turok)

The UFS also currently houses one SANRAL (Prof Loyiso Jita) and one ETDP SETA (Prof Pat Mafora) Research Chair in Mathematics and Science Education within the Faculty of Education.

The UFS Library and Information Services (LIS) has expanded its services during my tenure and is an invaluable resource that underpins our scholarship. Over the past ten years, we have embraced rapid technological advances and global trends in Information Science. The newly established Centre for Digital Scholarship provides a one-stop facility for academics, support staff, and students to access the many resources available at the university. It supports and develops the research and teaching needs of staff and students in the digital environment.

Postgraduate students

The growth in postgraduate student numbers during my tenure is particularly gratifying. The number of doctoral students has approximately doubled (from 531 in 2012 to 1 042 in 2022), and the number of postdoctoral fellows has more than tripled (from 64 in 2012 to 214 in 2021). Postgraduate students contribute significantly to the UFS’ research efforts, and our output and growth in postgraduate student numbers reflect the institute’s increasing visibility as a centre of innovation and competitive research.

The UFS Centre for Graduate Support (formerly Postgraduate School) has expanded and evolved over the past decade. It has taken on additional administrative and support functions that provide streamlined and comprehensive support to postgraduate students – from application to graduation. Its Research Capacity Development Programme assists master’s and doctoral students through academic writing interventions, funding, and the monitoring of student progress using the innovative Graduate Research Management (GRM) system. Five provincial outreach and seven international research capacity development workshops were held in the period under review, and 289 academic writing consultations took place.

International Affairs

During the past decade, we have developed a vision for comprehensive internationalisation at the UFS, with a specific focus on research and innovation. Internationalisation of the curriculum, virtual exchanges, and co-curricular internationalisation at home activities have become entrenched at the university. We focused on developing new partnerships and collaborations in Africa, while continuing to strengthen our ties with the Global North. International student services and administrative processes have been renewed and aligned under the leadership of the Office for International Affairs (OIA). The OIA was reimagined as a strategic enabling centre for the institutional internationalisation process.

Investment in equipment for flagship focus areas

The past decade has witnessed considerable investments in upgrading the infrastructure and equipment of UFS research facilities. These interventions have contributed to placing us at the forefront of several research disciplines. Recent developments and acquisitions (among others) include

• high-resolution Orbitrap mass spectrometer for the South African Doping Control Laboratory (SADoCoL) worth R10 million;
• X-ray system for the Department of Physics, representing the first of such equipment on the African continent;
• advanced electron microscopy instruments that make the UFS an undisputed leader in this field, worth R65 million;
• biosafety Level (BSL) 3 laboratory in the Department of Medical Virology for the study of zoonotic diseases;
• upgrading the laboratories and infrastructure of the National Health Laboratory Service and the Animal Research Centre; and
• development of an Innovation Hub on the Paradys Experimental Farm.

Increasing NRF and third-stream income

During my tenure, the university managed to more than double its income from NRF research activities, from R25 919 231 in 2012 to R65 811 564 in 2022. 

Various innovative ways of generating valuable, sustainable third-stream income were also launched and expanded during this period, resulting in our generated income being recorded in 2022 at an impressive R107 537 743. 

In conclusion, it has been a privilege to lead the Research and Internationalisation portfolio of the UFS over the past decade. I have enjoyed the support of a strong team central to our research development efforts. Their hard work has been pivotal in advancing the institutional vision of a student-centred and regionally engaged university that contributes to development and social justice through the production of globally competitive graduates and knowledge.

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.
