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.

Prof Luyt says young researchers should not allow circumstances to determine their future

Young researchers, who spend their life at a disadvantaged and rural campus like the University of the Free State’s Qwaqwa Campus, should not be deterred from achieving their dreams.

This is the view of Prof Riaan Luyt, former Assistant Dean in the Faculty of Natural and Agricultural Sciences, who achieved his B-rating by the National Research Foundation (NRF) late in 2015. This was by far the highest-ever rating on the Qwaqwa Campus.

“When I moved to the Qwaqwa Campus many years ago, having had the opportunity to do a post-doctoral fellowship in Polymer Science at the Leeds University in the United Kingdom, I was determined to get the Department of Chemistry off the ground, and to embark on serious research,” said Prof Luyt, who is now the Affiliated Professor in the Department of Chemistry and Research Associate Professor at the Centre for Advanced Materials, based at Qatar University.

“It was through sheer determination that I managed to obtain enough funds to equip a decent research laboratory. There were many obstacles over the years, but I managed to attract more and more postgraduate students and published more,” he said.

At first, Prof Luyt was not successful with his NRF-rating applications.

“My first couple of attempts to get rated produced no success. I was then awarded a C3-rating, which was later followed by C2 and then C1,” he added. “Getting a B-rating is the highlight of my research career. It shows that it can be done. Young researchers should not allow their past or present circumstances, or their work environment to stand on their way,” said Prof Luyt, who has supervised 38 master’s and doctoral students as well as 11 postdoctoral fellows. He has also published 185 papers in international and accredited journals.

Although abroad, Prof Luyt will continue to supervise eight postgraduate students at the Qwaqwa Campus.
