Prof Robert Bragg
Area of expertise: Microbial, Biochemical and Food Biotechnology
Faculty/Department: Natural and Agricultural Sciences, Microbial, Biochemical and Food Biotechnology

Prof Robert Bragg and his research team from the Department of Microbial, Biochemical and Food Biotechnology at the UFS are regarded as world leaders in their area of research. Prof Bragg is a C-rated NRF researcher.

In a major breakthrough, his team have been able to produce a vaccine against a virus which cannot be cultured. The technology is now used as a model for their other vaccine development projects. His main research focuses on control of diseases, mostly in the veterinary field.

His long-standing and current research areas focus on infectious coryza caused by the bacterium Avibacterium paragallinarum which occurs in poultry, disease control in a post-antibiotic era and vaccine development. They are assisting vaccine producers in South Africa, India and Israel to improve the formulation of vaccines, and are investigating variant field isolates from countries in South and Central America. Resistance to disinfectants are also being investigated.

The other research area in which the group is active is the search for disease control options in a post-antibiotic era. He has been working towards this for many years and the focus has been on improved biosecurity and the development of a continual disinfection programme in poultry. This work was based on a novel disinfectant which was produced by a South African company based in Stellenbosch. This was the first use worldwide of a disinfectant to control disease in poultry production. It was demonstrated that this continual disinfection programme could stop serious poultry diseases such as Newcastle disease virus and Avian influenza, another current “hot topic”. This work resulted in the registration of a disinfectant with label claims for the control of Newcastle disease virus. This was another “first” for a disinfectant. This continual disinfection programme will be the only viable solution to control bacterial diseases in poultry production in a post-antibiotic era.

His main research activity is on the control of diseases in birds (mostly poultry) and in efforts to improve vaccination efficacy, particularly for the often neglected small-scale farmer.

Prof Felicity Burt 
Area of expertise: Medical Virology
Faculty/Department: Health Sciences, Medical Microbiology

Prof Felicity Burt is from the Division of Virology, in the Faculty of Health Sciences at the University of the Free State (UFS) and National Health Laboratory Services (NHLS). She currently holds a NRF-DST South African Research Chair in vector-borne and zoonotic diseases.  Professor Burt and her research group investigate arboviruses and zoonotic viruses. 

The research primarily focuses on host immune responses to arboviral infections specifically characterising humoral and cellular immune responses in patients with infections such as Crimean-Congo haemorrhagic fever (CCHF) virus and Sindbis virus; epitope discovery for development of diagnostic tools; development of molecular and serological assays for surveillance purposes; virus discovery; and development of vaccines. Raising awareness of these viruses, defining associated diseases and developing tools for surveillance programmes will contribute to understanding these pathogens and the public health implications.

Arboviruses cause outbreaks of disease in South Africa annually. Outbreaks are usually associated with heavy-rainfall favouring mosquito-breeding, but these viruses also have the capacity to spread and become endemic in new areas where competent vectors are present. 
In addition, she is leads a research group that investigates human papilloma viruses (HPV) associated with head and neck cancers and recurrent laryngeal papillomas.

The focus of this research group is to ascertain the genotypes of HPV causing these diseases, identification of novel biomarkers for early detection and complete genome sequencing for molecular characterisation of HPV isolates.  

Prof Philippe Burger
Area of expertise: Economics
Faculty/ Department: Economic and Management Sciences, Economics and Finance
 
Prof Philippe Burger is a Professor of Economics and Head of the Department of Economics at the University of the Free State (UFS). He was a 2016/17 Fulbright Exchange Scholar at the Center for Sustainable Development, Earth Institute, at Columbia University (New York).

He was president of the Economic Society of South Africa from September 2012 to October 2014. Prof Burger is also a member of the South African Statistics Council, which oversees the work of Statistics SA. His publications include three books and numerous academic articles on fiscal rules and fiscal sustainability, public private partnerships and macroeconomic and economic development policy.

Together with International Monetary Fund (IMF) staff he co-authored two IMF working papers. In 2009 the IMF invited him to spend a month at the IMF as a visiting scholar. In 2007, 2010 and 2012 he was seconded to the Organisation for Economic Cooperation and Development (OECD) in Paris to work on public private partnerships and capital budgeting. In October 2011 he joined an OECD mission to Indonesia to conduct a regulatory review of Indonesia. He was a member of the Panel of Experts of the South African National Treasury, in which capacity he co-authored a 20-year review of South African fiscal policy since 1994.

Dr Francois Deacon
Area of expertise: Habitat Ecology
Faculty/Department: Natural and Agricultural Sciences, Animal, Wildlife and Grassland Sciences

Dr Francois Deacon is a wildlife habitat expert, among other things, but his research is focused on giraffe in their natural habitat. The recognition he has earned nationally and internationally is proof of that. He has a saying: “If we can save the habitat wildlife need, then the animals will be just fine”.

He has received a National Research Foundation (NRF) grant and various other funding to support his research on an international level. He was nominated on multiple occasions as the best lecturer at the UFS and the students truly enjoy his teaching philosophy that: “not all classrooms have four walls”.

Dr Deacon is a lecturer at the Department of Animal, Wildlife and Grassland Sciences in the Faculty of Natural and Agricultural Sciences. Dr Deacon considers himself as a habitat ecologist, focusing on the spatial ecology of wild mammals. He has many projects with collaborations from institutions worldwide, but his primary project is to understand the ecological and biological factors that regulate giraffe in their natural habitat. For this he has built a multispecialist research team of 30 scientists from 10 different countries, helping to address the research questions and objectives.

His long-term research and contribution to save the giraffe from becoming extinct in the wild on the African continent has received extensive coverage in the popular press and has led to three wildlife documentaries made on his research by National Geographic and presentations at international conferences. With his spatial ecology approach, he evaluates the habitat preferences, diet selection and spatial utilisation by giraffe in different reserves across Southern Africa. The successful development of a head harness equipped with a satellite GPS device was an exceptional achievement with more than 50 giraffes contributing to the success. This led to the collection of data and the description of behaviour that has never before been documented. The development of scientific norms and a management manual not only resulted in a unique study of significant academic importance, but will also contribute to the effective management and conservation of the species in Africa.

He has published in a few international journals and aims to continue to publish in high-impact factor journals. His latest expeditions are considered as the key of all keys and could create a turnaround of giraffe numbers plummeting further. An international film crew are busy capturing this process in a film called Catching Giants in which the UFS is the true leader and brainchild of this pioneer study.

Dr Sethulego Matebesi
Area of expertise: Local politics
Faculty/Department: The Humanities, Sociology

Dr Sethulego Matebesi is a Senior Lecturer in the Department of Sociology, says, “South Africa has experienced widespread community protests driven by historical conditions and contemporary pressures.” Dr Matebesi is involved in work that combines research and advocacy work on social movements, protests, governance and public participation at local government level, and mining in South Africa. He is a regular commentator on local socio-economic and political issues in the country.

Dr Matebesi published Civil strife against local governance: Dynamics of community protests in contemporary South Africa, in March 2017. The book is based on a three-year project funded by the National Research Foundation (NRF) and responds to the challenging question of how ratepayers’ associations in predominantly white areas and concerned groups in predominantly black communities use different protest tactics in response to the same set of grievances.

His earlier work on service-delivery protests has exposed him to political and social commentary for the SABC and various independent radio stations since 2009.

Prof Marian Tredoux
Area of expertise: Mineral Geology
Faculty/ Department: Natural and Agricultural Sciences, Geology

Prof Marian Tredoux is a geochemist in the Department of Geology at the UFS. This means that she is interested in rocks, particularly the chemistry of rocks and the minerals of which they are composed are chemicals similar to those found in laboratories, although they occur in nature.

She started her research career at the University of the Witwatersrand (Wits), after which she spent a number of years at the University of Cape Town (UCT). For the past 11 years, she has been at the UFS, which has brought her in close proximity to her primary field research area, in Barberton. This fascinating part of the country has been the focus of Prof Tredoux's research for 30 years, and she has been intrigued by the earth's crust in this area, which she describes as "very old, very strange, and very interesting".

Prof Tredoux has been collaborating with colleagues and peers overseas in an attempt to unravel the intricacies of this unusual geologic area. Some of these colleagues recently discovered a new mineral in one of the rock formations of the Barberton mountainland. They decided to name this mineral after Prof Tredoux, dubbing it tredouxite. She says, "I am very honoured by this, and very grateful that all these many years of collaboration are being acknowledged."

Prof Corinna Walsh
Area of expertise: Nutrition and Dietetics
Faculty/Department: Health Sciences, Nutrition and Dietetics

Globally, it has become apparent that health in both children and adults is closely related to the early environment that children are exposed to during pregnancy and early childhood, says Prof Corinna Walsh  of the Department of Nutrition and Dietetics and an National Research Foundation C-rated researcher at the University of the Free State (UFS).

Prof Walsh has a keen interest in health research, specifically nutrition and health epidemiology. She has initiated three large-scale health and nutrition-related surveys that have been instrumental in determining the burden of disease in the Free State, related to both infectious and lifestyle diseases. The morbidity and mortality resulting from these diseases have reached epidemic proportions in developing countries such as South Africa, and are thus an important area of investigation.

The focus of her research is on nutritional health, HIV, malnutrition, food security, and transitions from traditional to Western lifestyles and how these impact on health. Collaboration with co-workers from Basic Medical Sciences, Chemical Pathology, Haematology, Biostatistics, and others ensures a strong emphasis on interdisciplinary research.

Her datasets have been included in three international meta-analyses to answer key questions related to cardiovascular risk in HIV-infected and uninfected people. These have been published in high-impact journals such as BMC Medicine and International Journal of Epidemiology.

She says the study of the early environment can contribute to understanding the mechanisms by which disease manifests later in life. In this regard, she has initiated a birth cohort study within the Faculty of Health Sciences. This multidisciplinary longitudinal study will investigate the short- and long-term consequences of early environment in a group of mothers and children from the Free State for years to come.

Prof Walsh has received the Nutrition Society Best Young Scientist Award and the Association for Dietetics Community Dietetics Award. She serves on the Ethics Committee of the Faculty of Health Sciences, and is a council member of the Nutrition Society of South Africa. Between 2005 and 2010, she served on the Board of the Medical Research Council, gaining valuable experience in health research and research administration.
