Prof Liezel Lues, Professor in the Department of Public Administration and Management at the University of the Free State (UFS), has been elected as the President of the International Association of Schools and Institutes of Administration (IASIA).

The election took place on 14 October 2025 in Mexico City during the IASIA Board of Management meeting, where Prof Lues received an overwhelming 22 out of 25 votes. Describing her appointment as the pinnacle of her public service career, she reflected.

“It is a moment where hard work, dedication, and unwavering focus have truly converged, and I am deeply grateful to all those who have supported my growth and opened doors along the way.”

Prof Lues, whose term will run until 2028, was nominated by former IASIA President Dr Najat Zarrouk and endorsed by Prof Ing. Juraj Nemec, Chairperson of the International Commission on Accreditation of Public Administration (ICAPA).

Leading global collaboration in public administration

As IASIA President, Prof Lues will provide leadership and strategic direction for the association's affairs, overseeing 127 international organisations across 56 countries. Her responsibilities include appointing - subject to the approval of the incoming Board of Management - seven Vice-Presidents representing each global region: Africa, Latin America and the Caribbean, the Middle East, Asia, Europe, North America, and Australia.

In addition to these duties, she will be travelling extensively to strengthen global partnerships and advance IASIA’s mission of promoting excellence in public administration education and practice.

A vision for a forward-looking IASIA

Prof Lues shared that her motivation to accept this leadership role stems from a desire to contribute strategically to global collaboration and research - particularly in empowering women in academia and public service.

“As a woman in academia and leadership, I was motivated by the need to model representation and inspire others to step into leadership spaces traditionally dominated by men,’’ she explained.

Looking ahead, she envisions steering IASIA towards a more agile, forward-looking institution. Her priorities for the next three years include:

Promoting and maintaining a collegial and collaborative organisational culture;
Embracing digital transformation and innovation;
Fostering cross-disciplinary, impactful research; and
Investing in sustainable institutional development and rehabilitation strategies.

Drawing from her extensive experience - first in government and later in academia - Prof Lues expressed confidence in her ability to lead the association into a new era.

“I am confident that my vision will build on the association's previous successes and elevate it to new horizons in the coming terms,” she said.

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.

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast 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.
