High-profile positions at National Treasury, the World Bank and now also the International Monetary Fund in Washington, mark an illustrious career for UFS Economics alumna, Vuyelwa Vumendlini.

“Go in full force, hands and feet, and accept this opportunity of a lifetime. You won’t regret it.” These words of Dr Minette Smit, her thesis supervisor, proved to be pivotal advice to a young Vuyelwa Vumendlini. At the time, she was doing her BCom Honours in Economics (1996-1999) and was presented with a scholarship opportunity to complete her master’s degree in the USA.

“I was afraid to leave my home and my comfort zone,” she explains. “But looking back, I’m extremely grateful to have taken that step.”

Her studies culminated in an appointment as Senior Adviser to the Executive Director at the World Bank, then Deputy Director-General: International and Regional Economic Policy at the National Treasury, and now as Alternate Executive Director at the International Monetary Fund (IMF) in Washington DC. As an IMF executive board member, Vumendlini represents 23 English-speaking African countries that are members of a constituency. The Executive Board of the IMF has 24 chairs, representing 24 constituencies from its 189 countries’ membership. Among her duties are considering policy issues and surveillance reports, as well as approving and monitoring IMF programmes involving lending and/or technical assistance.

Since this is the second stint in Washington for her and her children, Simphiwe, Enhle, and Anele, settling down was much easier. “Because of the COVID-19 isolation, we were kind of used to being alone at home, so we didn’t find the solitude that bad while we were still making new friends.”

She misses South African food the most – things like biltong and boerewors – and the proximity of favourite restaurants like Ocean Basket and Mugg & Bean. She has fond memories of her study years, working as an assistant in the Department of Economics, hanging out at Mooimeisiesfontein on Saturdays, and building rag floats for Vergeet-My-Nie and Kestell residences. Plans for the future include tackling her PhD in Economics.

Her advice to UFS students: “Be up to date with what is happening around you. Do not be afraid to do things differently. Be agile in your approach to achieving your career aspirations and be ready to take on those opportunities when they present themselves.”

Lithium-ion batteries research set to improve ordinary lives
2016-02-11

Dr Koao is making a much-needed contribution in improving lives of ordinary people through his research on lithium-ion batteries.

The future of relevant and top-notch scientific research at the Qwaqwa Campus is in good hands. Dr Lehlohonolo Koao is one of the five members of the Vice-Chancellor’s Prestige Scholars Programme (PSP) on the Qwaqwa Campus.

The need to improve the efficiency of heating mechanisms in his immediate community in Qwaqwa, and the support he receives from the PSP, have become catalysts for his current research project on lithium-ion batteries. According to Dr Koao, the study will focus on producing batteries that last longer, store more energy, are cheaper to manufacture, and are environmentally friendly when being disposed of. These are key factors in solar energy.

‘’The majority of households in my neighbourhood have benefited from the government’s project of providing households with solar panels to help with lighting, cooking, and heating without worrying about the ever-increasing electricity costs,’’ said Dr Koao.

‘’Since my arrival in the area, I have realized that the heat absorption rate of the batteries used by solar panels is not enough. As a result, these batteries also lack enough power to sustain the supply throughout the day, especially on a cloudy day,’’ he said.

His research project focuses on improving the efficiency of lithium-ion batteries that are now commonly used in portable electronics, such as cell phones and laptops. This kind of battery is rapidly replacing the usual lead-acid batteries. Dr Koao’s determination to contribute towards a safer and more efficient heating absorption system has made him move away completely from his PhD study on lighting material.

‘’My previous study was on reducing the power usage on domestic and industrial lights as they use more electricity. This study, on the other hand, will enhance power retention in the batteries for improved daily life since cell phones, solar panels, and laptops, to mention only a few, are now a way of life,’’ he added.

Dr Koao is a Senior Lecturer in the Department of Physics, where he specializes in solid state materials.
