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.

The newly established virology section at the University of the Free State (UFS) boasts world class expertise. Not only are they one of just five laboratories in the country tasked with specialised HIV testing, but current research generates publications and subsidised funding.

The driving force behind this initiative is passionate and dedicated people who invest long hours into vital research. One such person is Prof Felicity Burt, who eloquently guides her students while making impressive progress within her own field of interest: vector-borne and zoonotic diseases. Prof Burt was recently awarded a research chair (2016-2020) to, among other areas, investigate medically significant vector-borne and zoonotic viruses currently circulating.

That means that her research focus is mainly on viruses transmitted by mosquitoes and ticks, and viruses transmitted from animals to humans. “Yes,” she laughs, “I catch mosquitoes and check them for viruses.”

Becoming familiar with different viruses
As if big screen moments like Outbreak and Contagion did not create enough virus paranoia, the world was recently bombarded by real world Ebola and Zika outbreaks. But awareness, Prof Burt says, is not a bad thing. “Years ago, when people heard that I did Ebola research, they got that distant look in their eyes, and changed the subject. One outbreak later, backed by many media reports, and Ebola is almost a household name. The same goes for the recent Zika virus outbreak in South America.”

The more familiar people become with these types of viruses, the better, Prof Burt feels. However, getting the right message across is not always that easy. The Zika virus outbreak, for example, was a very large outbreak and therefore presented large numbers of affected people. Generally, not everyone infected with an arbovirus will necessarily present with symptoms. But because vector-borne viruses can spread to new areas, surveillance and awareness is important. Here in Bloemfontein, Prof Burt and her team are establishing surveillance programmes.

Gaining knowledge and preventative measures
So, next time you get all wound up about a “biological disaster”, rest assured that competent people like Prof Burt and her colleagues continuously scan the environment to gain knowledge and develop preventive measures should any risks be looming. For example, developing next-generation vaccines that are very effective, but without risk – since they are not built on the virus itself, but only on the part of the virus that will induce an immune response.

Currently, Prof Burt is also looking into the relationship between the Sindbis virus and arthritis. It is clear that we can expect many exciting findings from the UFS’s new virology unit.
