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.

Twenty-years ago, after a person had been diagnosed with HIV, their lifespan did not exceed three years, but thanks to the success of antiretroviral therapy programmes, life expectancy has risen by an average of ten years. However, is antiretroviral therapy always going to be for life? This is the societal issue that Professor John Frater, addressed in his talk at the University of the Free State. He is an MRC Senior Clinical Fellow, Associate Professor and Honorary Consultant Physician in Infectious Diseases at  Oxford University.

Antiretroviral medicine therapeutic

The discovery of antiretroviral therapy - the use of HIV medicines to treat the virus - has had a positive effect on the health and well-being of people living with it, improving their quality of life. Unfortunately, if treatment is stopped, HIV rebounds to the detriment of the patient. Now, research has shown that some patients, who are treated soon after being infected by HIV, may go off treatment for prolonged periods. Work is being done to predict who will be able to stop treatment.

“The difference made by starting treatment earlier is enormous. Delaying treatment is denying yourself the right to health,” Professor Frater says. However, this does not mean that the virus is cured. “A person can live for ten years without being on HIV treatment, but is that enough?” he went on to ask.

Healthy lifestyles encouraged

The National Department of Health will adopt a test and treat immediately strategy later this year to improve patient health and curb the spread of HIV. ,This is another reason why everybody should know their status and start treatment as soon as possible.

Search for a cure continues

More research is being conducted to establish whether HIV can be eradicated. Remission gives hope that a permanent cure may be found eventually. “Will a cure for HIV ever be found? Time will tell,” he concluded.
