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.”

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Profile of the gravitational waves of the colliding black holes.

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
