Dr Herkulaas Combrink is representing UFS in a new international research project that aims to improve how evidence is used in public health policymaking.

Dr Herkulaas Combrink, a senior lecturer in the Faculty of Economic and Management Sciences (EMS) at the University of the Free State (UFS), is representing the university in a new international research project that aims to improve how evidence is used in public health policymaking.

Dr Combrink, who is also a co-director of the Interdisciplinary Centre for Digital Futures (ICDF), has been selected as one of the principal investigators in a newly funded project supported by the UK’s International Science Partnerships Fund under the Evidence-Informed Policymaking Programme. Running from April 2025 to March 2026, the project – titled Integrating Evidence for Contextualised Public Health Policy: Lessons from South Africa – explores how different types of evidence can be used more effectively in shaping public health policy. The international collaboration includes researchers from the Centre for Philosophy of Epidemiology, Medicine and Public Health, which is a collaboration between Durham University and the University of Johannesburg; as well as Durham’s Centre for Humanities Engaging Science and Society.

 

From the Free State to global impact

For Dr Combrink, being part of this collaboration highlights the important work being done in the faculty and ICDF that is reaching beyond borders. 

“It’s important to showcase the impact we are making from the Free State that leads to global outcomes,” he said.

The project aims to evaluate an evidence mapping framework to determine how model-based projections and social listening reports can be more effectively integrated and contextualised for policymaking.

“These are two very different data types,” he explained. “The value lies in demonstrating how to apply the framework to different contexts for evidence-based mapping.”

Dr Combrink brings extensive expertise to the team, having worked on both disease modelling and risk communication during South Africa’s COVID-19 response. He was involved in national and provincial social listening initiatives, and used high-frequency social media data to track the spread of misinformation, often referred to as the ‘infodemic.’ 

“We’ve built up enough data within ICDF and EMS to support this study,” he noted.

The goal is not just theoretical. A key outcome of the project is engaging directly with policymakers to refine modelling and risk communication strategies for future pandemics. 

“This will help us to engage with the various departments of health to assist with improving modelling and risk communication work for better social behavioural change,” he explained.

According to Prof Brownhilder Neneh, Vice-Dean for Research and Internationalisation in the EMS faculty, the project reflects the faculty’s growing global presence. 

“Dr Combrink’s participation is a testament to the calibre of scholarship within the faculty,” she said. “It positions EMS as a key contributor to shaping policy and practice with societal impact.”

She added that the collaboration aligns well with the faculty’s vision for global partnerships that are rooted in local relevance.

“By focusing on contextualised evidence for policymaking, this project reflects our commitment to relevance, engagement and global partnership,” she said.

 

What comes next

Over the project’s 12-month timeline, the team will deliver:

• a case study analysis of modelling and social listening during South Africa’s COVID-19 response;
• an extended evidence mapping framework tailored to diverse evidence types;
• policy briefs and practical tools for public health practitioners; and
• a hybrid international workshop in late 2025 bringing together researchers, policymakers and health professionals to test and refine these outputs.

Researcher at Qwaqwa Campus, Dr Aliza le Roux, selected as SAYAS member
2014-09-12

 

Dr Aliza le Roux

Dr Aliza le Roux, senior lecturer in the Department of Zoology and Entomology on the Qwaqwa Campus of the University of the Free State (UFS), was selected as a member of the 2014 South African Young Academy of Science (SAYAS). Dr Le Roux, a member of the Vice-Chancellor's Prestige Scholars Programme at the UFS, is also a South African National Research Foundation-rated (NRF) scientist (Y2) and the winner of the UFS Vice-Chancellor’s Excellence in Teaching Award in 2013.

She sees her selection to SAYAS as a unique opportunity to help change the face of science in South Africa. Dr Le Roux hopes to use her skills as project leader in social media, as well as her own learning experiences on a rural campus, to inspire especially ecological research in a country so rich in its own natural heritage.

The SAYAS selection committee was impressed by the high level of academic merit and depth of the nominations they received. “Your membership is critical in contributing to many of the vital activities and functioning of SAYAS, and we look forward to your active contributions to the further development and growth of the Young Academy,” said Prof Aldo Stroebel, Chair: SAYAS Selection Committee.

Prof Corli Witthuhn, Vice-Rector: Research at the UFS, said, “Aliza le Roux is an outstanding young scientist on our Qwaqwa Campus. She is not only an outstanding researcher but has also received prizes during the past year for her dedication to teaching. I am very excited about the young researchers on our Qwaqwa Campus with Aliza as one of the leaders, and I am looking forward to what else they can achieve in the next five years.”

In the past decade, Dr Le Roux focused her research on the cognitive and communicative skills of wild mammals in South Africa and Ethiopia. She spent four years as a postdoctoral research fellow at the University of Michigan, leading to ground-breaking research on the cognitive and communicative underpinnings of gelada monkey behaviour. Her current work encompasses an NRF-funded project on paternal care in bat-eared foxes, and experimental research on spatial cognition in wild samango monkeys. She is also involved in discussions with the Endangered Wildlife Trust to research the mitigation of road-kill incidents in South Africa.

Dr Le Roux hopes to combine cognitive ecology with more applied conservation questions in order to raise the profile of behavioural ecology as a discipline. She believes strongly in involving the public with scientific research, and has blogged for Nature Magazine on her adventures as field biologist. Her work has since found its way into numerous websites, magazine and newspaper articles and she has been interviewed on radio and BBC World.

Dr Le Roux will be inaugurated as SAYAS member on 14 October 2014.

Dr Marieka Gryzenhout from the Department of Plant Sciences is also a member of SAYAS.
