WomenofKovsies Dr Lize Joubert on flowers and their favourite insects
Pollination is important to maintain diversity in our natural ecosystem and maintain ecosystem health

“Pollination is important to maintain diversity in our natural ecosystem and maintain ecosystem health.” So says Dr Lize Joubert, lecturer in the Department of Plant Sciences at the University of the Free State. “Research helps to understand the interaction between insects and flowers and their many implications on real-world problems.”

Plant systematics and pollination biology, Dr Joubert’s research field, looks at how plants diversify, adapt to environmental changes and how their flowers evolve to keep attracting insects to pollinate them for reproduction. 

Dependency on pollination

Crop production is, in many cases, dependent on pollination. About 75% of the world’s crops are to some extent dependant on pollination. “Pollination is really important for us as human beings, but it is also important to maintain diversity in our natural ecosystem and maintain ecosystem health.”

Dr Joubert obtained her PhD in plant systematics in 2013 and was subsequently awarded the EM van Zinderen-Bakker Prize for an outstanding PhD dissertation in Botany.

She is also the curator of the Geo Potts Herbarium in Bloemfontein, the internationally accredited herbarium housing over 30 000 plant specimens, mainly representing the flora of central South Africa and several special collections from Marion Island, the Okavango Delta, and KwaZulu-Natal. 

Learning from the experts

As a young researcher Dr Joubert became part of the Prestige Scholars Programme (PSP) at the UFS which led her to Cambridge University where she became part of a research group for nearly two years under an expert in her field, Prof Beverley Glover. The PSP at UFS identifies and promotes promising young academics at the university to become full professors with excellent research accomplishments. 

Dr Joubert views the PSP Programme to a large extent as her academic home. She is proud to be part of the programme that has brought her closer to other experts in her field and resulted in collaborations in which she is involved in cutting-edge research.

Otorhinolaryngology research hopes to decrease morbidity

Otorhinolaryngology at the UFS

Prof Riaz Seedat, Head of the Department of Otorhinolaryngology at the UFS is a world-renowned ear, nose and throat specialist and researcher. He is also a National Research Foundation C3 rated scientist.

He is conducting his research in ear, nose and throat (ENT) pathology in a developing world setting, particularly focusing on recurrent respiratory papillomatosis and other ENT conditions. “This condition is caused by human papillomavirus (HPV), infective conditions as well as allergic rhinitis,” said Prof Seedat.

Current research is aimed at further describing the epidemiology of recurrent respiratory papillomatosis, identification of the HPV variants responsible for causing the condition and markers of disease aggressiveness.

The research has led to various international partnerships such as the multicentre collaborative studies, “Genetic Susceptibility to Papilloma-induced Voice Disturbance” at the Centre for Genomic Sciences at the Allegheny-Singer Research Institute in Pittsburgh, United States, and the HPV6/11 Global Diversity Consortium at the University of Ljubljana in Slovenia.

Although most head and neck squamous cell carcinomas are caused by excessive tobacco and alcohol use, there is an increasing body of evidence to show that HPV causes a subset of head and neck squamous cell carcinomas. However, there are few studies on the role of HPV in head and neck neoplasms in developing countries.

“Through the research we have shown that recurrent respiratory papillomatosis, caused by HPV, is not as rare in South Africa as it is in developed countries and that patients usually present respiratory papillomatosis at an advanced stage when the condition is life-threatening,” said Prof Seedat.

“It is hoped that this research will help us to address the morbidity caused by ENT conditions common in developing countries,” said Prof Seedat.
