The Council of the University of the Free State (UFS) approved the appointment of Prof Philippe Burger as Dean of the Faculty of Economic and Management Sciences for a five-year term during its quarterly virtual meeting on 26 November 2021. 

He is Pro-Vice-Chancellor: Poverty, Inequality and Economic Development, as well as Vice-Dean (Strategic Projects) of the Faculty of Economic and Management Sciences, and Professor of Economics at the UFS. 

Extensive experience

Prof Burger was a 2016/17 Fulbright exchange scholar at the Center for Sustainable Development, Earth Institute, Columbia University in the United States, with Prof Jeffrey Sachs as his Fulbright host, where he wrote a book titled Getting it right: a new economy for South Africa. The book was launched, with presentations at the International Monetary Fund (IMF), World Bank, and RAND Corporation in Washington DC, among others. In addition, he is a member of the Fiscal Policy and Financial Markets Task Team of the Lancet Commission on COVID-19. Co-chaired by the Head of the IMF’s Department of Fiscal Affairs and a former Minister of Finance of Chile, the task team of 11 members comprises economists from across the world, including two Nobel prize winners. 

From September 2012 to October 2014, Prof Burger was President of the Economic Society of South Africa. His publications include three more books and numerous academic articles on fiscal rules and fiscal sustainability, public-private partnerships, and macroeconomic and economic development policy. Together with IMF staff, he co-authored two IMF working papers. In 2009, the IMF invited him to spend a month at the IMF as a visiting scholar in the Fiscal Affairs Department (FAD), researching public-private partnerships and the Global Financial Crisis. For two months each in 2007, 2010, and 2012, he was seconded to the Organisation for Economic Co-operation and Development (OECD) in Paris, France, to work on public-private partnerships and capital budgeting, while in October 2011 he joined an OECD mission to Indonesia to conduct a regulatory review of Indonesia. 

Prof Burger was a member of the Panel of Experts of the South African National Treasury, in which capacity he co-authored a 20-year review of South African fiscal policy since 1994. From 2013 to 2018, he was a member of the South African Statistics Council, which oversees the work of Statistics South Africa. From 1 February 2018 to 31 January 2019, he acted as dean of the Faculty of Economic and Management Sciences at the UFS, and from 2002 to 2019 he was Head of the UFS Department of Economics. 

“With more than 27 years of experience in the higher-education sector, Prof Burger will bring a wealth of expertise, extensive networks, and partnerships, nationally and abroad, to the Faculty of Economic and Management Sciences and the UFS. His experience in the positions held at the university, as well as his extensive knowledge and understanding of the South African and global economy, places him in good standing to lead the faculty to be a formidable and impactful academic force nationally and abroad,” said Prof Francis Petersen, UFS Rector and Vice-Chancellor. 

“Prof Burger has the competencies required as dean of the Faculty of Economic and Management Sciences, leading it to exploit opportunities and deal with the challenges that the rapidly changing world presents to the UFS,” said Prof Petersen.  

Vision for the faculty

In response to his appointment, Prof Burger said, “I am humbled by this appointment and look forward to taking on this wonderful challenge. The faculty has a strong team of academics and administrative staff. With this team, I know we will create wonderful pathways for our students into the future and into the complex world of work. I also look forward to strengthening our research position and building the faculty as a nationally and internationally recognised research-strong faculty, as well as a faculty with a very strong Global South presence.”

Prof Burger succeeds the current Dean, Prof Hendri Kroukamp, who will be retiring at the end of February 2022.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
