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.

From Neanderthal hybrid children to eating corn silk as a way of managing kidney diseases, the National Three Minute Thesis competition (3MT) captivated the mind.

“We brought the competition to South Africa and hosted the local, regional, and national competitions for the past few years,” said Dr Emmie Smit, organiser of the event. It is an opportunity to raise the profile of postgraduate research and to develop a cross-disciplinary student community to effectively communicate research to a wide audience. The event was founded by the University of Queensland, Australia. The third national 3MT competition took place at the University of the Free State (UFS) on Friday 24 March 2017.

Three minutes and one slide
During the competition, participants had three minutes to explain their master’s or doctoral research and one static PowerPoint slide could be used. “It is very important that this slide works for you. There must be some way the information on the slide connects to what you present,” said Dr Henriette van den Berg, Director of the Postgraduate School at the UFS.
 
Winners grateful for opportunity
“It is an honour and a drive. It is very nice to have this sort of thumbs up,” said Kerryn Warren, winner of the Science category. Her research title was, What did a Human-Neanderthal Child Look Like? “I have been looking at the hybrids between different species and subspecies of mice in order to use them as a model to find out what human hybrids looked like.”

The presentation by Andrew Verrijdt, winner of the Humanities category, entitled Hiding in the Deep: Anonymous Websites for Paedophiles on the ‘Darknet’, gave a glimpse into the mysterious and dangerous realm of the dark web. “I am grateful for the opportunity. Primarily because I think it’s an important topic, and society will benefit by getting the word out there as it is a sensitive topic,” he said. The two winners, both from the University of the Cape Town, won R15 000 each.  A further R30 000 of prize money went to the four runners-up.
