The University of the Free State is proud to introduce three esteemed academics who have been appointed as Vice-Deans within the Faculty of Natural and Agricultural Sciences. These appointments, effective from 1 September 2023, mark a significant milestone in enriching our academic leadership and promoting excellence in teaching, research, and innovation. The distinguished individuals selected for these roles bring a wealth of experience, expertise, and dedication, promising to elevate our institution to new heights.

Prof Johan van Niekerk: Vice-Dean for Agriculture

Prof Johan van Niekerk is a prominent figure in the field of Sustainable Food Systems and Development. With a PhD in Sustainable Agriculture and extensive experience in academia, Prof Van Niekerk is well-positioned to lead as the Vice-Dean for Agriculture at the University of the Free State. He has a strong vision for steering the Faculty of Natural and Agricultural Sciences towards financial sustainability and global recognition. 

One of Prof Van Niekerk's primary goals as Vice-Dean is diversifying funding sources for the faculty, aiming to extend beyond government funding by establishing strategic partnerships with industries and foundations. His active involvement in regional and global agricultural forums underscores his commitment to collaborative research initiatives, further enhancing our faculty's reputation. 

In response to the pressing issue of climate change, Prof Van Niekerk's research vision is centred on sustainable agricultural production. He plans to leverage the Paradys Experimental Farm, integrating research, teaching, and practical experiences to fortify our foundation for sustainable agricultural innovation. This approach is designed to equip our students for a rapidly evolving employment market and aligns with the university's Vision 130 and the UN Sustainable Development Goals (SDGs). 

On his appointment, Prof Van Niekerk said, “I am excited about this position's prospects and am confident that agriculture will help deliver the SDGs and the UFS Vision 130. I look forward to contributing to the continued success of the Faculty of Natural and Agricultural Sciences.” 

Prof Liezel Herselman: Vice-Dean for Teaching and Learning 

Prof Liezel Herselman, a distinguished academic with nearly three decades of experience, has assumed the role of Vice-Dean for Teaching and Learning. Her extensive academic journey, including various leadership roles within the university, showcases her dedication to education and academic advancement. 

In this vital role, Prof Herselman will focus on strategic matters, curriculum innovation, and compliance with academic regulations. Her objective is to align the curricula with Vision 130, making the Faculty of Natural and Agricultural Sciences the preferred choice for prospective students. Prof Herselman emphasises digital transformation and entrepreneurial projects to provide a cutting-edge educational experience for students, ensuring they meet industry needs and are ready for future employability challenges.

On assuming her new position as Vice-Dean Prof Herselman said, “I am honoured and excited about receiving this opportunity to make a positive and constructive contribution to our faculty. I am still to learn the ropes of some of the teaching and learning processes, but I am looking forward to expanding my knowledge and having to move out of my current comfort zone.” 

Prof Samuel Adelabu: Vice-Dean for Research and Postgraduate Studies 

Prof Samuel Adelabu, an esteemed expert in Geography, has been appointed as the Vice-Dean for Research and Postgraduate Studies. Prof Adelabu has a profound interest in the application of remote sensing and geographic information systems, making him well-suited to lead research and postgraduate activities within the Faculty of Natural and Agricultural Sciences. 

His portfolio includes promoting impactful research and postgraduate initiatives in line with the university's Vision 130, with a special focus on visibility, renewal, and reimagination. Prof Adelabu's leadership is anticipated to foster a thriving research culture and enrich the postgraduate experience at the UFS. 

Commenting on his appointment Prof Adelabu remarked, “I am excited about the opportunity to bring my expertise and leadership as Vice-Dean for Research and Postgraduate Studies to the faculty, and work with a team of dedicated professionals to advance the institution's research and postgraduate agenda.” 

Future endeavours 

These appointments underscore the university’s unwavering commitment to fostering a culture of excellence, research innovation, and enhanced learning experiences. The collective expertise and dedication of Prof Johan van Niekerk, Prof Liezel Herselman, and Prof Samuel Adelabu promise a bright future for their respective faculties and the university at large. We extend our hearty congratulations and eagerly anticipate the positive impact they will bring to our academic community.

Link between champagne bubbles and the UFS?

What is the link between the bubbles in champagne and breakthrough research being done at the Mayo Clinic in America? Nano research being done at our university.

Prof. Lodewyk Kock of Biotechnology says a human being consists of millions of minute cells that are invisible to the eye. The nano technology team at the UFS have developed a technique that allows researchers to look into such a cell, as well as other microorganisms. In this way, they can get an idea of what the cell’s “insides” look like.

The UFS team – consisting of Profs. Kock, Hendrik Swart (Physics), Pieter van Wyk (Centre for Microscopy), as well as Dr Chantel Swart (Biotechnology), Dr Carlien Pohl (Biotechnology) and Liza Coetsee (Physics) – were amazed to see that the inside of cells consist of a maze of small tunnels or blisters. Each tunnel is about 100 and more nanometres in diameter – about one ten thousandth of a millimetre – that weaves through the cells in a maze.

It was also found that these tunnels are the “lungs” of the cells. Academics doing research on yeast have had to sit up and take notice of the research being done at the UFS – to the extent that these “lungs” will appear on the front page of the highly acclaimed FEMS Yeast Research for all of 2013.

The Mayo Clinic, in particular, now wants to work with the UFS to study cancer cells in more detail in order to fight this disease, says Prof. Kock. The National Cancer Institute of America has also shown interest. This new nano technology for biology can assist in the study and development of nano medicine that can be used in the treatment of cancer and other life threatening diseases. Nano medicine uses nano metal participles that are up to one billionth of a metre in size.

Prof. Kock says laboratory tests indicate that nano medicine can improve the efficacy of anti-cancer medicine, which makes the treatment less toxic. “According to the Mayo Clinic team, nano particles are considered as a gold cartridge which is being fired directly at a cancer tumour. This is compared to fine shot that spreads through the body and also attacks healthy cells.”

“This accuracy implies that the chemotherapy dose can be lowered with fewer side effects. The Mayo Clinic found that one-tenth of the normal dosage is more effective against pancreas cancer in this way than the full dosage with a linkage to nano particles. According to the clinic, this nano medicine could also delay the spread of cancer,” says Prof. Kock.

The nano particles are used as messengers that convey anti-cancer treatment to cancer cells, where it then selectively kills the cancer cells. The transport and transfer of these medicines with regard to gold nano particles can be traced with the UFS’s nano technology to collect more information, especially where it works on the cell.

“With the new nano technology of the UFS, it is possible to do nano surgery on the cells by slicing the cells in nanometre thin slices while the working of the nano medicine is studied. In this way, it can be established if the nano medicine penetrates the cells or if it is only associated with the tiny tunnels,” says Prof. Kock.

And in champagne the small “lungs” are responsible for the bubbles. The same applies to beer and with this discovery a whole new reach field opens for scientists.
