Prof Liesl van As
Prof Liesl van As, Academic Head of the Department of Zoology and Entomology, is passionate about equal rights for parasites.

As a research-led institution, the university has 1 600 female researchers (2019 statistics), with 63 boasting ratings from the National Research Foundation (NRF). Four of the UFS SARChI Research Chairs are also headed by women. 

One of the scientists at the University of the Free State (UFS) who gets excited about research is Prof Liesl van As, Academic Head of the Department of Zoology and Entomology

She was part of the UFS team that established Africa’s largest digital laboratory, equipped with 227 microscopes, to ensure that undergraduate students from Zoology and Entomology, as well as Plant Sciences (Faculty of Natural and Agricultural Sciences), have access to hi-tech equipment for a cutting-edge teaching experience.

The good and the bad 

But she also has a passion for her own research – that of fish parasites. Her most recent research work is about the biodiversity of fish parasites in natural river systems, with a focus on the Orange River and its tributaries, as well as the Okavango River and Delta in Botswana.

A few years ago, the Department of Agriculture, Forestry and Fisheries expanded their mandate for fisheries management by adding inland fisheries and aquaculture to their list of responsibilities. 

Prof Van As believes her research will add value to this process. “If we are going to expand inland fisheries, we need to expand our knowledge of what is happening in natural systems. It is important that we know and understand what potential problems might arise in aquaculture conditions.”

Equal rights for parasites

“We also need to understand that not all so-called parasites are bad, some have co-evolved with their hosts and they are part of our overall biodiversity. If the hosts are going extinct, so does this amazing spectrum of symbionts,” says Prof Van As, who is enthusiastic about promoting ‘equal rights for parasites’ (Wilson, 1995). 

When it comes to the future of women in research, Prof Van As – inspired by life itself, believes the possibilities are endless. “If you can dream it, you can do it. Ex Africa Semper Aliquid Novi (out of Africa there is always something new),” she states.

Art and science help us understand the world and our place in it

Although BioArt dates back as far as the 15th and 16th centuries with the work of Leonardo da Vinci, it is not every day that art and science combine. This rare phenomenon made its appearance when two totally different groups of students – studying arts and microbiology respectively – joined hands in an initiative to create BioArt.

This first-time undergraduate teaching collaboration between the Departments of Fine Arts and Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS), which is characterised by the use of living materials, such as enzymes, microbes and DNA, as well as scientific tools and methods, is exploring a number of questions. 

Different outcomes for arts and microbiology students

According to Prof Carlien Pohl-Albertyn from the Department of Microbiology, Biochemical and Food Biotechnology, one of the central questions explored in BioArt is the nature of ‘life’. “At which stage can matter be classified as being alive or living?” she asked. 

“We realised that the outcomes for the two groups of students would not be the same. For the microbiology students, the focus would be on the understanding and effective communication of a microbiological concept. For the art students the focus would be on the execution of the assignment using visual elements and applied theory of art,” said Prof Pohl-Albertyn.

Dr Janine Allen-Spies from the Department of Fine Arts added: “Art students will also be exploring strangely or previously unforeseen gaps between art and science that can be filled with imaginative interpretations which may forward creative insights in both BioArt as a developing art form and microbiology as investigative science.”

Students’ understanding of microbial evolution reflected in art
The art students had to visit the microbiology labs for their assignment as this is mostly a foreign environment for these students. “The paint medium they had to use was gouache. This medium with its bright colours works well to depict microscopic organisms in art,” Dr Allen-Spies said. 

On display at the Department of Microbial, Biochemical and Food Biotechnology on the Bloemfontein Campus, at a recent event to introduce this new initiative to a wider audience, was a range of visually and scientifically compelling paintings and artefacts (such as paintings, poems, songs, apps) which explore a theme within microbiology from a BioArt perspective that uses creativity to communicate concepts dealt with in the module Microbial Evolution and Diversity.

Any parties who are interested in buying the art can contact Dr Allen-Spies at allenj@ufs.ac.za.

Paintings and artefacts reflects students understanding of BioArt. At the recent opening of the BioArt exhibition at the UFS Department of Microbial, Biochemical and Food Biotechnology, was the work of Madeleen Jansen van Rensburg on display.

Pheny Mokawane, a Microbiology, Biochemical and Food Biotechnology student, wrote a poem for his BioArt project in the Microbial Evolution and Diversity assignment.
