Dr Thandi
After nearly seven years Dr Lewin finally graduates with a PhD.

Dr Thandi Lewin has spent the past six-and-a-half years of her life on her PhD.  It was only in the final year of the process that the thesis came together. “I had a few chapters and had done literature reviews and some theoretical work, as well as a little initial analysis, but none of it actually added up to a coherent thesis. The moment when I realised that I actually did have a thesis was a great feeling and a huge relief because it was only then that the end was in sight,” she said. 

On Wednesday 11 December 2019 her diligence culminated in a graduation ceremony at which she obtained her PhD in Higher Education Studies in the Faculty of Education at the University of the Free State (UFS). Dr Lewin formed a part of the pioneering cohort of the South African Research Chairs Initiative (SARChI) Chair in Higher Education and Human Development Research Programme, under the leadership of Professor Melanie Walker

Through the twists and turns

Working on her thesis on Early career women academics: A case study of working lives in a gendered institution, Dr Lewin struggled with time constraints. “I could not work on it every night or every early morning like some people do. My job was demanding, so I worked most nights and often went to bed quite late. Hence, I failed to focus on it during the week,” she explained.

When she began her PhD her youngest child was one year old. In addition to her job becoming more and more challenging over the years, Dr Lewin also had to maintain a morning and evening routine in order to make the most of the limited time she and her family had together. Yet after all was said and done, her research still beckoned.

Reaching the stage of walking across the stage

Given the rigorous process of completing a PhD, one of the major motivators was her supervisor. “Prof Walker was loyal and never gave up on me. She was also pragmatic and understanding. The commitment from a supervisor who is considerate of your personal circumstances, but is also as dedicated to your research project as you are, is quite something to find.”

For much of the past three years of her doctorate, Dr Lewin’s father was ill. He eventually succumbed to his illness in January 2019. The graduate struggled with managing her emotions as she felt guilty about not spending enough time with him due to work and research. “Being a mum and a daughter meant that if I wasn’t at work or working on my PhD I was with my kids or with my dad. But I must also acknowledge that my partner, nanny, and part-time housekeeper provided critical support which I couldn’t have done without.”

On gender and organisational cultures

The Chief Director for Institutional Governance and Management support in the university education branch of the Department of Higher Education and Training found the experience garnered in the system-level of higher learning enormously helpful in her research process.   “I have really enjoyed working in an area that interests me, and engaging with a topic that is policy-relevant,” she said.

Cultivating culture change

Enabling women to rise through the ranks would require more effort to improve gender equity. “Organisations and universities can never really achieve gender equity without fundamentally changing their structures and cultures, which are deeply gendered. This also cannot happen without social change, which needs to take place in broader society and not only within organisations,” said Dr Lewin.

What this means for society and organisations is a shift from focusing solely on individual women. According to Dr Lewin: “Universities, in addition to their inclination towards slow change, are also experienced by many as exclusionary – not just by women, but by people of colour and those from working-class backgrounds, and others who have been traditionally marginalised in higher education. This is a critical issue for South African higher education – it is going to take a lot of time and focused commitment to change the cultures of universities to be more inclusive.”

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
