The Council of the University of the Free State (UFS) approved the appointment of Prof Heidi Hudson as Dean of the Faculty of the Humanities during a meeting on the Bloemfontein Campus on 22 January 2018. She assumed office on 1 March 2018.

Prof Hudson is a Professor of International Relations with a PhD in Strategic Studies, and has been recognised for her undisputed international standing, which resulted in the awarding of a B2 rating by the National Research Foundation, effective from 1 January 2018. She was co-editor of The International Feminist Journal of Politics for the past six and a half years, as well as a Global Fellow of the Peace Research Institute in Oslo (2014-2016). Prof Hudson currently serves on the Advisory Board of the African Peacebuilding Network at the Social Science Research Council in New York. In 2018, she will also be the Claude Ake Visiting Chair, hosted by the Department of Peace and Conflict Research, Uppsala University and the Nordic Africa Institute. Her Claude Ake Memorial Lecture will focus on the decolonisation of gender and peacebuilding in Africa. 

“Prof Hudson is a well-respected researcher and senior manager and will add immense value to the faculty. She has been associated with the UFS for almost 25 years and the institutional memory she brings to the position is indispensable. I look forward to working with her and to support her in realising her vision for the faculty,” says Prof Francis Petersen, UFS Rector and Vice-Chancellor. 
 
Prof Hudson started her academic career at the UFS, spent six years at the former University of Durban-Westville (1991-1996), after which she re-joined the Department of Political Science at the UFS, where she was Departmental Chairperson from 2006 to 2007. In 2009, she joined the Centre for Africa Studies as Africa Studies programme director (2009-2011), and has been the Director of the centre since September 2012. The centre was recently externally evaluated and the positive report testifies to her leadership. Prof Hudson managed to increase the centre’s international footprint in a short space of time and effected an increase in research outputs, as well as PhD enrolment and output.   
 
In addition to serving on the Faculty Committee of the Humanities, she is a long-standing member of the Faculty Research Committee and also chaired the Portfolio Committee on Quality Assurance (2005-2008), while also serving on the UFS Quality Assurance Committee (until 2008). She was Senate representative on the Institutional Forum (August 2013–July 2017) and a member of the UFS Gender Committee (until 2006). She was recently nominated to serve on the Senate Research Committee.
 
Prof Hudson has been acting in the position of Dean: Faculty of the Humanities since 1 October 2017. Her vision for the faculty includes, among others, curriculum renewal, interdisciplinary research, and improved governance at middle-management level.

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.
