EMS PhDs
Dr Shaun Watson, Prof Philippe Burger, Dr Marese Lombard, and Dr Ambrosé Du Plessis.

As the University of the Free State (UFS) continues to celebrate the achievements of its graduates during the April 2025 graduation ceremonies, three academic staff members from the UFS Faculty of Economic and Management Sciences (EMS) are among those marking a significant milestone with the successful completion of their doctoral degrees.

Prof Philippe Burger, Dean of the EMS Faculty, reflected on the significance of the moment and applauded the trio of new EMS PhD graduates: Dr Shaun Watson, Dr Marese Lombard, and Dr Ambrosé Ray du Plessis.

“For the EMS Faculty to have three staff members obtain a PhD on one day is very special,” Prof Burger said. “These colleagues have grown their standing in the scholarly community and are now, with a PhD in the bag, ready to take on the academic world and the world at large. The EMS Faculty places a high premium on our staff holding a PhD, so we strongly encourage those who are not in possession of a PhD to pursue one.”

Prof Burger added that their achievements not only reflect personal dedication and professional growth but also contribute to the University of the Free State’s Vision 130 goal: to have 75% of academic staff holding doctoral degrees by 2034.

The EMS academics who graduated during the April 2025 ceremonies are:

 

Dr Shaun Watson: Understanding markets through restatements

Dr Shaun Watson, a senior lecturer in the UFS School of Accountancy since 2006, earned his PhD in Management Accounting with a thesis titled ‘Market Efficiency and Share Price Reaction Following the Retrospective Restatement of Financial Statements of JSE-Listed Companies’. His study analysed how financial restatements affect market behaviour, providing key insights for policymakers and investors navigating emerging markets.

“For me, it was both a personal challenge and a professional goal,” Dr Watson said. “I’d often wondered if I had what it takes to complete a PhD and, as an academic, I saw it as the pinnacle of our field. My wife was the one who told me to ‘Nike – just do it!’ Her belief in me, along with the quiet support of my family, gave me the push I needed to start, and the strength to keep going.”

To those still considering the journey, Watson offered this advice: “Do it for yourself – because if you don’t, you will never finish. It is a demanding journey that requires sacrifice and perseverance, but the reward of discovering something meaningful is worth every moment.”

 

Dr Marese Lombard: Taxation as a tool for sustainable agriculture

Also from the School of Accountancy, Dr Marese Lombard received her PhD in Taxation. Her research, ‘Taxation as a Method to Promote Sustainable Agriculture in South Africa’, is the first of its kind to offer empirical evidence on how tax provisions could be used to incentivise sustainability in local agriculture.

“I hope to see a conversation regarding policy changes as to how taxation can be used as a positive method to impact sustainability,” Dr Lombard said. “If taxation can be used to further assist our agricultural industry to become more sustainable, it can not only increase our competitive edge but also address the concern of food security.”

Reflecting on her personal growth, she said, “It has taught me that we are more resilient than we think. The challenge of taking on a PhD has made me more open to other ideas and approaches, and more comfortable with criticism – not just in academia, but in life.”

 

Dr Ambrosé Ray du Plessis: Rethinking the political-administrative divide

From the Department of Public Administration and Management, Dr Ambrosé Ray du Plessis earned his PhD in Public Administration and Management. His thesis, ‘The Political-Administrative Dichotomy in Coalition-Led Metropolitan Municipalities: A South African Perspective’, developed a fresh conceptual framework for understanding the tensions and complexities within coalition-led governance, using the City of Johannesburg as a case study.

“For me, academia is a calling, and I believe that a PhD is an essential stepping stone to be successful in academia,” Dr Du Plessis said. “Being the first in my family to do a PhD motivated me to work harder, as I wanted to inspire those who will come after me.”

Balancing full-time lecturing and doctoral research required immense discipline: “I often had to work at night and over weekends to meet my deadlines… but the emotional and intellectual support from my PhD promoter, Prof Liezel Lues, was central to my success.”

Now, Dr Du Plessis hopes to deepen academic discourse on coalition politics: “My research addresses critical gaps and provides fresh insights into the political-administrative discourse as it can be applied to real-world coalition government problems in South Africa… I hope my work can leave a lasting impact – not only within academia but also in practical applications that benefit society.”

 

A testament to resilience and purpose

While their research topics differ vastly, all three describe their PhD journeys as transformative, both professionally and personally. From late nights and weekend writing sessions to intense supervision relationships, each story reflects a deeper commitment to scholarship – and to growing the UFS’s intellectual capital.

The field of Nuclear Medicine in South Africa and the rest of the world are expanding rapidly due to the development of hybrid cameras and new radiopharmaceuticals. These developments have a huge impact on the diagnosis and therapy of cancer.

The most advanced of these cameras, Positron emission tomography combined with normal CTs (PETCT), are not yet widely available in South Africa due to the cost of the cameras and the radiopharmaceuticals. A more cost-effective alternative can be of great benefit. To achieve this, the focus should be on developing new radiopharmaceuticals that can be used with the current cost-effective gamma cameras, according to University of the Free State researcher, Dr Je’nine Horn-Lodewyk from the Department of Nuclear Medicine.

Fluorodeoxyglucose (18F-FDG), a radiolabelled glucose analogue, is currently the radiopharmaceutical most commonly used in PET/CT imaging for mainly oncology indications. Although it is considered the gold standard for imaging in several malignancies, it does have certain disadvantages. An 18F-FDG PET/CT diagnostic imaging study can cost between R25 000 and R35 000 for a single patient in the private sector. The 18F-FDG is also more radioactive, which requires much stricter handling and shielding to avoid high radiation dosages to staff and patients.

Successful research potential innovative solution
In the search for the ideal radiopharmaceutical for tumour detection, the South African National Nuclear Energy Corporation (Necsa) developed a local synthesis process for ethylenedicysteine-deoxyglucose (EC-DG). EC-DG is also a glucose analogue similar to FDG. They succeeded in labelling the compound with Technetium-99-metastable-pertechnetate (99mTcO4-), the most common nuclear medicine isotope used for approximately 95% of nuclear medicine procedures, creating 99mTc-EC-DG.

In partnership with Dr Horn-Lodewyk, this compound was successfully used in various animal models and clinical scenarios, resulting in approval by the Medicine Control Council to use it in a human study. Research is also planned in order to investigate diagnostic accuracy in other cancers like lymphoma.  The end result of this research can produce a radiopharmaceutical that is cost effective, does not require the use of costly specialised equipment, has no significant side-effects, no special patient preparation, renders late imaging possible, and has decreased radiation risks.

Dr Horn-Lodewyk is grateful for the support of her mentor, Prof Anton Otto, as well as Dr Gert Engelbrecht, Head of the Department of Nuclear Medicine, Prof Jan Rijn Zeevaart from North-West University’s Preclinical Drug Development Platform and Necsa, and Judith Wagener from Necsa. This innovative research would also not have been possible without the financial assistance of Dr Glen Taylor and Eleanor van der Westhuizen in the Directorate of Research Development.
