Dr Ocaya
Dr Richard Ocaya’s research addresses the skills development and transfer millennium goal of many governments globally.

With the Fourth Industrial Revolution becoming a reality, Dr Richard Ocaya’s research is receptive to the fact that Africa and the world need to re-imagine their research. His research focuses on electronic instrumentation design for scientific measurements, computational physics on atomic nano-atomic structures, and semiconducting organic compounds materials built on silicon to realise Schottky devices.

Software developer 
“I develop most of the instrumentation that I apply in my research – both software and hardware,” said Dr Ocaya, a Physics Lecturer and Programme Director: Physics and Chemistry on the UFS Qwaqwa Campus.

“I am active in scientific computing through the computing cluster and software development, mathematical physics for material science modelling, and embedded instrumentation design using microprocessors. I also have deep interest in radio and data telemetry, in which I hold a South African patent issued in 2013. My present international collaborations are with like-minded researchers in similar fields in Saudi Arabia, Turkey, Japan, Egypt, South Korea, and the United States,” he added.

How does his research talk to the real world?
“The driving principle of all areas of my research has always been to deploy cutting-edge research to actual, real-world applications for the immediate betterment of Africans. The areas of my research align closely with the millennium goals of many governments globally, including the Republic of South Africa. These goals pertain to skills development and transfer that position us to better address the challenges of energy, water, and other priorities.”

Dr Ocaya is currently co-promoting a PhD student, having previously supervised one PhD, two MSc, and more than twenty honours students. He is a self-taught electronics and computer programmer, whose curiosity led him to question ‘the voices and music coming from a box; a radio’. “In my quest to satisfy my curiosity, I collected many discarded devices, took them apart, and tried so many circuits, only to have them fail because the theory was lacking. After thousands of failed projects and with me barely thirteen and in lower secondary school, my first ever project actually worked,” he said.

NRF-rating
He is the author of the book Introduction to Control Systems Analysis using Point Symmetries: An application of Lie Symmetries, which is available in all major bookstores such as Amazon, in both print and e-book format. He is a C3 NRF-rated researcher whose work makes a pioneering contribution to the new and growing field of phononics, an independent field of the now established photonics.

“This field will someday lead to improved energy-storage devices and faster processors due to more efficient heat removal from nanodevices,” he concludes.

UFS doctors fight childhood cancer

Of 23 paediatric oncology specialists nationally, Prof David Stones and Dr Jan du Plessis of the University of Free State are the only ones in the province.

Committed to giving holistic care to their patients, the two doctors specialise in all types of childhood cancers, the most common being leukaemia, brain tumour, and nephroblastoma.

They describe the childhood malignancy as a lethal disease, unpredictability being its harshest trait. “With cancer, you can just never know. It precipitates and multiplies, and leads to the failure of other organs. You can just always hope, and keep trying,” said Du Plessis.

The paediatric oncology unit of the Universitas Academic Hospital, their unit, is the liveliest floor in the entire building. It is also the third busiest in South Africa, serving a demographic that spans the Free State and Northern Cape, as well as parts of North West, Eastern Cape and Lesotho.

Each year, the unit receives more than 100 new childhood cancer patients. In 2015, the unit had 113 newly diagnosed patients, an increase from 93 in 2014.

Lack of knowledge poses a serious challenge
According to the two experts, the lack of insight and awareness of the disease remain a big challenge to fighting it. “It is frustrating. Parents and family members don’t know anything about it. Nurses and doctors aren’t always clinically trained to pick up the early warning signs. By the time a diagnosis is made, life and death is on a 50% margin,” Stones said.

Poverty, a lack of resources, overcrowding and a range of health issues are other factors that have a profound effect on the diagnosis and treatment of the disease.

Making a contribution that will last
With a desire to see an improvement on life outcomes in the health sector, the team is focusing on educating the country’s doctors of tomorrow. Their unit is the only one in the country that actively involves medical students in an oncology unit, giving them practical experience and exposure to the individual cases each patient presents. They have also produced a substantial amount of research literature on childhood malignancies in South Africa as a developing country.

Driven by passion to see a better South Africa
The doctors are passionate about the work they do, and remain hopeful there will be a change in the incidence of childhood cancer   not just in decreased levels of the disease, but also in the overall state of well-being of young South Africans.
