Dr Omololu Aluko, Senior Lecturer in the Department of Biostatistics advances health research and collaboration during prestigious fellowship at Ghent University, Belgium.

Dr Omololu Aluko, Senior Lecturer in the Department of Biostatistics in the Faculty of Health Sciences at the University of the Free State (UFS), recently completed a prestigious short research stay at Ghent University in Belgium. The fellowship, hosted in April 2025, was awarded through the highly competitive Africa Platform of Ghent University Association (GAP) funding scheme, with additional support from the UFS International Office. 

A recognised expert in infectious disease modelling, particularly HIV/AIDS research in low-resource settings, Dr Aluko has devoted his academic career to using biostatistics to address pressing health challenges. His selection for this fellowship marks a significant achievement both for his individual research trajectory and for the broader ambitions of the Faculty of Health Sciences and the UFS.

 

Strategic steps towards international collaboration 

The opportunity for the fellowship was first announced in the UFS Digest Newsletter. Motivated by the potential for international collaboration, Dr Aluko began seeking a host at Ghent University whose interests aligned with his own. After several weeks of correspondence with various departments and researchers, a suitable academic collaborator agreed to host him. 

With a host confirmed, Dr Aluko submitted his application, which underwent a rigorous review and selection process. His proposal was shortlisted and ultimately approved. While Ghent University provided partial funding, supplementary financial support was secured through the UFS International Office. Dr Aluko credits the office’s assistance – especially the guidance of Mr Kagiso Ngake, Senior Officer: Partnerships – for helping him successfully secure the necessary resources. 

 

Advancing research in health data science  

During his time at Ghent University, Dr Aluko focused on the application of machine learning algorithms to address public health challenges – an increasingly important field within the Faculty of Health Sciences. His research demonstrated how advanced data analysis techniques can improve health outcomes and optimise treatment strategies, especially in resource-constrained settings. 

Beyond the immediate research achievements, the fellowship laid a foundation for long-term collaboration between the UFS and Ghent University. Key outcomes include: 

  • Opportunities for joint PhD supervision, allowing UFS students to conduct part of their research at Ghent University 
  • Prospects for publishing collaborative research in leading international A1-rated journals 
  • The identification of a promising young research collaborator, paving the way for future academic partnerships 
  • Plans to explore future staff exchange programmes, as new funding calls are announced 

     

A growing partnership in a new academic field 

Dr Annelies Verdoolaege, Coordinator for the Africa Platform at Ghent University, emphasised the broader vision behind the initiative:

“The purpose of these fellowships is to foster structural academic collaboration between Ghent University and partners in Africa. We offer a dedicated amount of seed funding to support short-term mobility, with the aim of building long-term partnerships – through student exchange, joint PhDs, joint funding proposals, and collaborative research publications. 

The UFS is a long-standing partner of Ghent University, especially in Education, Linguistics, and Agriculture. We are delighted that this fellowship has taken place in the field of Data Analysis and Mathematical Modelling - a scientific domain still to be fully developed between our institutions.” 

 

Enhancing UFS’ global research impact 

Dr Aluko’s successful fellowship reflects the high calibre of researchers at the UFS and illustrates the importance of international academic mobility. By securing this competitive opportunity, Dr Aluko not only advanced his own work but also strengthened the UFS’ global research footprint - opening new collaborative avenues and reinforcing the university's growing reputation in health sciences and data-driven research. 

The UFS expresses its sincere gratitude to the Africa Platform of Ghent University and the UFS International Office for their critical support in enabling this milestone. Partnerships such as this are key to fulfilling the UFS’ mission of producing world-class research and fostering meaningful global engagement.

Producers to save thousands with routine marketing strategies, says UFS researcher

Using derivative markets as a marketing strategy can be complicated for farmers. The producers tend to use high risk strategies which include the selling of the crop on the cash market after harvest; whilst the high market risks require innovative strategies including the use of futures and options as traded on the South African Futures Exchange (SAFEX).

Using these innovative strategies are mostly due to a lack of interest and knowledge of the market. The purpose of the research conducted by Dr Dirk Strydom and Manfred Venter from the Department of Agricultural Economics at the University of the Free State (UFS) is to examine whether the adoption of a basic routine strategy is better than adopting no strategy at all.

The research illustrates that by using a Stochastic Efficiency with Respect to a Function (SERF) and Cumulative Distribution Function (CDF) that the use of five basic routine marketing strategies can be more rewarding. These basic strategies are:
• Put (plant time)
• Twelve-segment pricing
• Three-segment pricing
• Put (pollination)(Critical Moment in production/marketing process), and
• Pricing during pollination phase.

These strategies can be adopted by farmers without an in-depth understanding of the market and market-signals. Farmers can save as much as R1.6 million per year on a 2000ha farm with an average yield.

The results obtained from the research illustrate that each strategy is different for each crop. Very important is that the hedging strategies are better than no hedging strategy at all.

This research can also be applicable to the procurement side of the supply chain.

Maize milling firms use complex procurement strategies to procure their raw materials, or sometimes no strategy at all. In this research, basic routine price hedging strategies were analysed as part of the procurement of white maize over a ten-year period ranging from 2002–2012. Part of the pricing strategies used to procure white maize over the period of ten years were a call and min/max strategy. These strategies were compared to the baseline spot market. The data was obtained from the Johannesburg Stock Exchange’s Agricultural Products Division better known as SAFEX.

The results obtained from the research prove that by using basic routine price-hedging strategies to procure white maize, it is more beneficial to do so than by procuring from the spot market (a difference of more than R100 mil).

Thus, it can be concluded that it is not always necessary to use a complex method of sourcing white maize through SAFEX, to be efficient. By implementing a basic routine price hedging strategy year on year it can be better than procuring from the spot market.
