Dr Marié Herbst
Dr Marié Herbst received her PhD with specialisation in Design, titled The (S)Pace of Images: establishing a practice of the conscious abstraction of motion. She hopes that the techniques and processes explored in her research will spark creativity in the way other designers approach their work.

“My research has unveiled the exquisite patterns generated by motion in nature and everyday objects – patterns that often evade our awareness as we encounter motion in a fleeting moment. Abstraction plays a pivotal role in unveiling these exquisite yet largely unnoticed patterns that surround us.”

This is the perspective of Dr Marié Herbst, who graduated at the University of the Free State (UFS) in December, receiving her PhD with specialisation in Design, titled The (S)Pace of Images: establishing a practice of the conscious abstraction of motion.

Abstraction, a key component of building design

Dr Herbst says that the abstract art movement has had a profound influence on how designers think about design. “Highly regarded architects such as Le Corbusier and Zaha Hadid identify their practice of creating abstract paintings as the driving force behind their ground-breaking building designs. Abstraction is therefore a key component of building design, although the process of how it is applied has historically not received adequate attention. My research explores the way abstraction enables designers to include design information that is only possible through the process of abstraction. One such aspect is motion. Through the process of tracing and superimposing still images extracted from films, I can integrate them into a single picture that shows the progression of time,” she explains.

She hopes that the techniques and processes explored in her research will ignite creativity in how other designers approach their work. “The concepts and techniques outlined in my research are intended to prompt other designers to reconsider the procedures they employ when crafting spaces,” she states.

In the future, Dr Herbst says, she would like to further explore the ideas sparked by her research, such as determining how design would be affected by recording movement in a three-dimensional environment. “New technologies such as LiDAR make the recording of three-dimensional information much simpler, and it will increasingly become a part of our everyday lives. This is a potentially useful information stream that could be applied to create novel designs,” she says.

‘Practice-based’ versus ‘design-led’ research

Prof Jonathan Noble, Head of the Department of Architecture, says this is the very first PhD from the new creative research programme in architecture that was launched in 2018, where the student has completed a ‘design-led’ enquiry. 

He explains that the new creative programme differentiates between ‘practice-based’ research, closely tied to real-world architecture, where candidates analyse and study their previous work, and ‘design-led’ research, which is led by an entirely new creative exploration that encourage speculation and experimentation. According to him, the latter leads to a creative enquiry, and this body of new work is analysed and written about.

Following Prof Noble, postgraduate research in architecture in South Africa has traditionally centred around architectural theory, cultural history, urban studies, and conservation. Creative research methods, however, have not been as prominent. The Department of Architecture is addressing this by introducing new postgraduate research modes supported by innovative research degrees, marking a departure from the traditional approach in South Africa.

“We believe the programme will have a lasting and significant effect upon our professional degrees, injecting professional creativity and new thinking into the life of the department, and serving as an opportunity to look deeply into design and pedagogic practices. Over time, the programme will strengthen ties with the profession and address the closed mentalities of the so-called ‘academic ivory tower’.”

“In addition to providing emerging young scholars with opportunities, the programme facilitates the documentation of the unique qualities of South African practice and makes an important contribution to future research publication and teaching pedagogy at the UFS and beyond,” he says.

Dr Charlotte Boucher and Lindi Heyns examine possible anti-microbial activity in the skin of Western olive toad species
2014-12-22

 

Researchers Lindi Heyns and Dr Charlotte Boucher are working together on an interdisciplinary project between the Departments of Zoology and Entomology and Veterinary Biotechnology at the University of the Free State (UFS). The focus of their research is on the preliminary biochemical description of skin secretions in some South African toads.

The project forms part of an Honours study executed by Dwayne Pike under Heyns’ supervision. He is co-supervised by Dr Boucher who is assisting with the biochemical and microbiological assays.

Dr Boucher said, “Amphibians are characterised by the presence of cutaneous glands spread over the skin. There are two types of glands, namely mucous and granular (poison), located on the inner surface of the epidermis. Mucous glands are widely dispersed over the skin, while granular glands can be grouped and enlarged in specific regions. Mucous glands are generally associated with maintenance of humidity and cutaneous respiration, whereas granular glands function in chemical defence against predators and/or microbial infection. Studies indicate that the compounds produced by the granular glands belong to numerous chemical classes with diverse pharmacological activities.”

The products secreted by granular glands are rich in low molecular weight constituents of varied molecular types, including proteins, peptides and toxins. These secretions make the toad foul-tasting to predators and even toxic to other frog species. In addition, amphibians offer an attractive source of novel antimicrobials. Studies indicate that as a response to inhabiting microorganism-rich environments they synthesise and secrete a diverse array of antimicrobial peptides (AMPs) as an innate form of defence. Extensive research by various other research groups has been carried out on antimicrobial peptides of the genus Rana; however, hardly any studies have investigated the antimicrobial activity of African frog species.

The focus of this preliminary project is to determine the protein composition of the glandular secretions of the Western olive toad (Amietophrynus poweri), using biochemical tests, such as SDS-PAGE also known as protein gel electrophoresis combined with mass-spectrometry used to identify unknown peptides and proteins. This will give us an overview of the composition of the glandular secretions. Furthermore, we are also looking at microbiological tests, which include assays that test for possible anti-microbial activity against various bacterial and fungal species.
