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.

#Women'sMonth: Lack of HIV education still affects children

“Despite all the advances in the management and prevention of HIV, children still become infected every day, often due to lack of education and access to health care.” This is according to Dr Nickie Goedhals, Senior Lecturer and Pathologist in Medical Microbiology and Virology at the University of the Free State (UFS).

Study published in UK medical Journal 
A case study she was part of and published in the UK medical journal The Lancet in 2012, demonstrates the transmission of HIV to a child through surrogate breastfeeding. This study is one of the many highlights in the young researcher’s career. She received her first rating from the National Research Foundation (NRF) in 2017 for the work she has done in Medical Virology over the past eight years.

According to the above-mentioned study, only about 1% of infants in South Africa are being breastfed by a surrogate. However, results from a study in the Free State showed that shared breastfeeding by a non-biological caregiver was the most important factor associated with HIV infection in discordant mother-child pairs. Therefore, continued education about the risk of HIV transmission is needed.

Dr Goedhals is also continuing with research on HIV by looking at HIV drug resistance. She is in the process of starting new projects focusing on HIV infection and drug resistance in infants.

PSP helped with NRF-rating
She says, although her NRF Y2-rating is the starting point of a research career, it shows that she is heading in the right direction, and it “gives access to research funds through the NRF for future projects.” Other important research she conducted was on Crimean-Congo haemorrhagic fever – the study for her PhD.

The Prestige Scholars Programme (PSP) at the UFS is the reason that she applied for the rating. “With all the service delivery, teaching, and administrative responsibilities of academic medicine, it is easy to lose focus. The PSP has really helped to create a focused and stimulating environment for research.” According to her, the PSP also provides access to a network of peers and senior staff at the UFS, as well as exposure to national and international experts.
