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.

Research into surrogate milk important to wildlife conservation

Research is being done at the University of the Free State (UFS) to analyse and synthetically imitate the unique milk of various wildlife species. This research is not only of scientific value, but also serves the conservation of South Africa’s wildlife species. At the forefront of this research is Prof Garry Osthoff from the Department of Microbial, Biochemical and Food Biotechnology.

Orphaned rhino calf pulled through with surrogate milk
“There is still a lot of research to be done. Naturally the research is of scientific importance, but with surrogate milk having the same composition as the mother’s milk of a specific species, orphaned calves or cubs of that species could be pulled through during a difficult time of weaning. Bearing in mind that exotic animals fetch thousands and even millions of rands at auctions, it goes without saying a game farmer will do everything possible to provide only the best nourishment to such an orphaned animal. In such a case, synthetically-manufactured milk would be the right choice,” says Prof Osthoff.

The fruits of his research were recently demonstrated in Germany when a rhino calf was left orphaned in the Leipzig Zoo. Prof Osthoff’s article: “Milk composition of a free-ranging white rhinoceros during late lactation” was used as a directive for applying surrogate milk for horse foals (which is already commercially available), since the composition of horse and rhino milk largely corresponds. The surrogate milk was used with great success and the rhino calf is flourishing. He mentions that such an orphan is often given the wrong nourishment with the best intentions, resulting in the starvation of the animal despite the amount of cow’s milk it devours.

Milk formula for baby elephants in the pipeline
With baby elephants left orphaned due to the increase in elephant poaching for their ivory, several attempts have been made to create a milk formula in order to feed these elephants. To date, many elephants have died in captivity from side effects such as diarrhoea as a result of the surrogate formula which they were fed.

Prof Osthoff recently received a consignment of frozen milk which he, together with researchers from Zimbabwe, will use to work on a milk formula for elephants. They are studying the milk in a full lactation period of two years. During lactation, the composition of the milk changes to such an extent that a single surrogate formula will not be sufficient. Four different formulas should probably be designed.

Prof Osthoff says that of the different species he has researched, elephants are the most interesting and deviate most from the known species.

Although his research to develop surrogate milk is adding much value to the wildlife industry, and although he finds this part of his work very exciting, his research focus is on food science and nutrition. “What is currently authentic in milk research is the study of the fat globules with content, the structure and composition of the casein micelle, and the prebiotic sugars. The knowledge which is gained helps to improve the processing, development of new food products, and development of food products for health purposes,” says Prof Osthoff.
