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.

Like Idols for scientists
2014-04-10

Kovsie student and scientist Karabelo Moloantoa recently represented the Free State in the South African finals of the FameLab competition during the Sci-Fest in Grahamstown.

Karabelo is a 24-year-old student doing his master’s in Biotechnology. He completed his Bachelor’s degree in Medical Microbiology, as well as his Honours degree in Biochemistry at Kovsies. His research is focused on Bioremediation of mine waste waters.

“FameLab is like the scientists Idols taking place annually,” says Karabelo.

“In the competition we are given three minutes to explain a science aspect to a non-science audience. There are 25 countries that participate. South Africa is the only African country participating.”

“I was called by one of my lecturers an hour before the local competition took place at the National Museum in Bloemfontein. I was actually still tired from playing volleyball the night before,” he explains. “I was unprepared and without slides, but I did my presentation.”

This was the first year Karabelo entered FameLab and although he was somewhat unprepared for the local competition in Bloemfontein, he was nominated to represent the Free State in Grahamstown at the Sci-Fest event. From the 18 semifinalists, Karabelo qualified to go the finals where the 9 finalists were competing to represent South Africa in the United Kingdom for the international finals.

“I did not win the UK trip, but I made it to the finals, which is an achievement as half of the semi-finalists could not make it to the finals,” says Karabelo.

“I feel like I have done well to represent the university and the province as a whole. It was amazing to speak in front of more than 800 people, delivering my presentation. I learnt a lot and improved my skills of communicating scientific aspects. I will definitely enter again next year.”
