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.

“Next time you have three minutes to spare, try to formulate your master’s or doctoral thesis,” says Dr Henriëtte van den Berg, Director of the Postgraduate School at the University of the Free State (UFS).

The much anticipated Three-Minute-Thesis (3MT) Competition took place at the UFS Bloemfontein Campus on Friday 19 August 2016. Diverse and interesting research projects were discussed, giving one a glimpse into months and even years of hard work and dedication.

A learning opportunity for candidates
The 3MT competition is an international event founded at the University of Queensland, Australia. It is divided into master’s and PhD categories.  At the UFS competition, the master’s section was dominated by the Medical and Natural Sciences, in contrast with the PhD section’s focus on Social Sciences. “The competition is a learning opportunity for our UFS candidates,” says Dr Henriëtte van den Berg.

Thought-provoking research presented
Interesting methodologies and research questions sustained the academic excellence the candidates pride themselves in. Saheed Sabiu, PhD candidate and winner, constructed his thesis around, Waste to Health: Corn silk in the Management of Kidney Diseases. “Use corn silk (white fibre around corn) in the same manner as a tea bag, to help manage kidney diseases,” says Sabiu.

Audience members also had the opportunity to ask the candidates questions relating to their thesis topic.

Winners at the event:
•    Master’s winner: Zingisile Mbo
•    PhD winner: Natural/ Health Science: Saheed Sabiu
•    PhD winner: Natural/Social Sciences: Thutukile Jita

The winners of each category received a cash prize and will represent the UFS at the national 3MT competition, hosted by the UFS in November this year.
