A data scientist and research coordinator at the University of the Free State (UFS), in collaboration with his supervisor at the University of Pretoria (UP), is at the forefront of the fight against the Covid-19 virus with accurate data and analysis.
Herkulaas Combrink of the Centre for Teaching and Learning at the UFS and PhD candidate in Computer Science at the UP, said accurate data is important to prevent widespread panic and sensationalism during a global disaster such as the current pandemic. This information helps people to make informed decisions and to reduce their exposure to the threat of the virus.

Assisting decision-makers

“I, along with colleagues from the World Health Organization, the Centers for Disease Control and Prevention in the USA, the provincial office of the Centers for Disease Control and Prevention, provincial clinicians, and the Free State Department of Health led by Dr David Motau, have been able to progress significantly in terms of evidence-based tools to assist provincial and national decision-makers during these turbulent times.”
“It does come at a cost, though, in that we have worked continuously since the lockdown, dedicating all our time and efforts to the department from all over to ensure that we are not part of some of the global statistics we have seen,” said Combrink. 

A paper written together with his supervisor, Dr Vukosi Marivate, has also been accepted by the Department of Higher Education and Training (DHET)-accredited Data Science Journal.  This paper is related to a framework for sharing public data to the public in a way that is useful, usable, and understandable. 

Ongoing projects

Combrink said it is hard to name all those who are/were involved in the great work done by the Free State Department of Health, but some of them include Dr Elizabeth Reji (Head of Department, Family Medicine), Dr Collin Noel (surgeon, senior lecturer at the UFS), Dr Sammy Mokoena (community health registrar, UFS), Dr Ming-Han Motloung (public health medicine specialist, senior lecturer, UFS), Dr Perpetual Chikobvu (Director: Information Management at the Department of Health, affiliated lecturer at the UFS), as well as Alfred Deacon (lecturer at the UFS), who have worked at some point during this short space of time on one of the many projects. 

Some of the projects include the following:

• A provincial database for screening and monitoring.
• A data pipeline and assembly of hospital information flow, liaised with the NICD, Vodacom, and the different district managers to ensure that the pipeline occurs in a timely manner.
• Digitised paper-based capturing tools for rapid data capturing and processing.
• Incorporated state-of-the-art visualisation tools to action data into useful information for decision-makers in certain areas.
• Provided both provincial and national projections, stress testing different scenarios using a variety of statistical, computational, and/or machine-learning approaches to add to the already existing projections of the Council for Scientific and Industrial Research (CSIR).
• Training healthcare professionals in the field to apply these tools within their own districts.
No easy task

“These aforementioned feats were by no means easy and are not completed yet, but we are getting there. In the foreseeable future, I will be working closely with national and international researchers to deploy a tool for hospital managers in the Free State that will assist them when we move from level 5 to any level below.”

“In addition to this, I am constantly providing support to the Free State Department of Health regarding any analysis required for decision-making purposes. The teams we work in comprise highly competent individuals with a passion for solving problems from multidisciplinary perspectives,” according to Combrink.

Christo Dippenaar knows the University of the Free State (UFS) very well. He started his studies at the UFS in 1992 and later obtained a BProc degree. During his years at university, he was Prime of Hendrik Verwoerd Residence (1994), served on the Student Representative Council in the portfolio Men Intern (1995), and in the following year he was Deputy President of the Student Representative Council. He was also residence head of the former Reitz Apartments.

A thorough knowledge of the university

Thanks to this broad background, he has a thorough knowledge of the university, its history, procedures, principles and its people. It is therefore no surprise that Dippenaar was elected to the Council by UFS alumni. Dippenaar, or “Dippies” as he is also known, has served on the Council since 2014. In addition, he has a child who is currently studying at the UFS and therefore he has more than just a theoretical interest in what is happening at the UFS.

He is of the opinion that, in his capacity as UFS councillor, he could be a true mouthpiece for former Kovsies.

"As councillor, I can ask the necessary questions to ensure fair and just treatment of all stakeholders."

A man with diverse interests
His legal knowledge also comes in handy in his role as councillor. Dippenaar was formerly employed at Honey Attorneys and at Horn and Van Rensburg, but in 2008 he started his own practice which is also operating in Lesotho.

He describes his wife, Hanlie, as his best friend and soul mate. His eldest son, Johann, is studying BSc Quantity Surveying at the UFS, while another son, Pieter, is in Grade 10 in Grey College. His daughter, Anneke, is in Grade 6 in Universitas Primary.

Asked about his passions, he says rugby and fine Brahman cross-breed cattle are equally attractive to him. Thus, a man with diverse interests and a highly demanding career, but also a former Kovsie with a passion for other former Kovsies and for his alma mater.
