The University of the Free State – Disaster Management Training and Education Centre for Africa (UFS-DiMTEC) welcomes the new permanent Director, Prof Abiodun Ogundeji.  

The Disaster Management Training and Education Centre for Africa, fondly known as ‘DiMTEC’, was established in 2000. Since then, the centre has been headed by Prof Andries Jordaan, who has created an impressive and expansive disaster risk management footprint in Africa and beyond for more than 17 years. Prof Jordaan retired in 2017, leaving the centre with huge shoes to fill. After several listings of the vacant position, a substantial appointment was only made in 2022 in Prof Abiodun Ogundeji as the new Director of DiMTEC. He will assume his new post on 1 March.

Extensive experience

Prof Ogundeji is an astute and versatile applied economist and National Research Foundation (NRF)-rated researcher. He obtained his PhD in Agricultural Economics from the University of the Free State. Before joining DiMTEC as Director, he was a guest lecturer presenting classes on the economic impact assessment of disasters and the management of floods. Prof Ogundeji was also Associate Professor in the Department of Agricultural Economics, where he presented classes and supervised master’s, PhD, and postdoctoral candidates.  

“As a researcher, I work with international and local organisations, leading most of the projects as principal investigator.  One of my greatest collaborations was when I was a research fellow at the social protection department of the Food and Agriculture Organisation of the United Nations (FAO); I believe the experience I gained from this association contributed to my career growth,” said Prof Ogundeji.

He has published 49 articles in peer-reviewed journals, delivered several conference presentations, supervised 14 master’s candidates, and promoted five PhD candidates in Agricultural Economics and Disaster Risk Management.
Prof Ogundeji's current research focuses on projects aimed at assisting farmers to adapt to extreme climate events, thereby ensuring food security. He recently completed a project as principal investigator, titled 'Development of scenarios for future agricultural water use in South Africa', sponsored by the Water Research Commission of South Africa. 

Prof Ogundeji has strong economic research and analytical skills, and a strong pedigree in econometrics, development and environmental economics, economic and socio-economic analysis. He has received awards for his research efforts at both national and international conferences.

“The faculty welcomes Prof Ogundeji as the new Director of DIMTEC. As an established, rated researcher, and with the vision that he presented during the interview, we are of the opinion that the centre is in excellent hands and that he will take it to new heights. As an agricultural economist, he replaces the previous director who was also an agricultural economist, filling the void created with the retirement of Prof Jordaan. He is familiar with the operational procedures of the centre, as he has been involved in the teaching of a module for several years. We therefore trust that the transition to a new management will be smooth,” said Prof Danie Vermeulen, Dean of the Faculty of Natural and Agricultural Sciences

“During my term of office, I had the privilege of working with Prof Ogundeji from as early as the time when he completed his master’s until he became a lecturer in one of the centre’s modules. I have seen him grow, and to date, we have partnered in several research projects. I am really happy about his appointment; academically it will bring a good balance between quantitative and qualitative focus in research. Most scientists in DiMTEC are mainly focusing on qualitative work, and Prof Ogundeji is excellent in quantitative research. He will continue where I left off as an agricultural economist and will bring back a good balance between economic impacts and disaster risk assessments. He has been lecturing with me for more than 15 years in Disaster Risk Assessments, which is a big module in the centre. He is very experienced and will be an excellent asset to the centre. I have no doubt that his appointment will move the centre to greater heights,” said Prof Jordaan.

One of UFS-DiMTEC’s long-serving Associate Professors from the United Nations University in Bonn, Prof Joerg Szarzynski, said “The United Nations University Institute for Environment and Human Security (UNU-EHS) congratulates Prof Ogundeji on his appointment as the new Director of DiMTEC! We are indeed looking forward to yet another decade of very fruitful collaboration between our institutes and all colleagues and friends involved.”

The long-term vision for disaster studies and research 

In response to his appointment and to shed more light on his vision for UFS-DiMTEC and the disaster management fraternity as a whole, Prof Ogundeji said, “It’s time for DiMTEC to take its position as the leading centre for disaster management and training in Africa, and as the gateway to Africa for other international organisations wanting to do research in Africa. I believe we have the personnel, passion, ability, and experience to serve the various stakeholders in South Africa and the international community.”

Mathematical methods used to detect and classify breast cancer masses

Examples of Acho’s breast mass
segmentation identification

Breast cancer is the leading cause of female mortality in developing countries. According to the World Health Organization (WHO), the low survival rates in developing countries are mainly due to the lack of early detection and adequate diagnosis programs.

Seeing the picture more clearly

Susan Acho from the University of the Free State’s Department of Medical Physics, breast cancer research focuses on using mathematical methods to delineate and classify breast masses. Advancements in medical research have led to remarkable progress in breast cancer detection, however, according to Acho, the methods of diagnosis currently available commercially, lack a detailed finesse in accurately identifying the boundaries of breast mass lesions.

Inspiration drawn from pioneer

Drawing inspiration from the Mammography Computer Aided Diagnosis Development and Implementation (CAADI) project, which was the brainchild Prof William Rae, Head of the department of Medical Physics, Acho’s MMedSc thesis titled ‘Segmentation and Quantitative Characterisation of Breast Masses Imaged using Digital Mammography’ investigates classical segmentation algorithms, texture features and classification of breast masses in mammography. It is a rare research topic in South Africa.

 Characterisation of breast masses, involves delineating and analysing the breast mass region on a mammogram in order to determine its shape, margin and texture composition. Computer-aided diagnosis (CAD) program detects the outline of the mass lesion, and uses this information together with its texture features to determine the clinical traits of the mass. CAD programs mark suspicious areas for second look or areas on a mammogram that the radiologist might have overlooked. It can act as an independent double reader of a mammogram in institutions where there is a shortage of trained mammogram readers. 

Light at the end of the tunnel

Breast cancer is one of the most common malignancies among females in South Africa. “The challenge is being able to apply these mathematical methods in the medical field to help find solutions to specific medical problems, and that’s what I hope my research will do,” she says.

By using mathematics, physics and digital imaging to understand breast masses on mammograms, her research bridges the gap between these fields to provide algorithms which are applicable in medical image interpretation.
