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.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
