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.

“Life is too short to abandon what sets you on fire. Find your passion, work hard at it and be great. You will never look back and wish otherwise.” These are the words that postgraduate student Charissa Worthmann lives by, and which have encouraged her to pursue her dream of being a gymnast.

Humble beginnings
After undergoing heart surgery earlier this year, Charissa bounced back stronger than ever. She went on to win five regional gold medals at the Free State Gymnastics Championships in February 2017 and was also crowned Free State Victrix Ludorum. In October 2016 she won a gold medal for her apparatus routine at the South African GymnasticsChampionships.

Charissa, who is currently doing her honours in Biokinetics at the University of the Free State (UFS), said coming from a small town was not always an advantage. “I come from a small town in KwaZulu-Natal where there are not many opportunities. Therefore there was no gymnastics. I found my natural talent, but never had the opportunity to develop it before coming to the UFS.”

Inspired by lecturer
Charissa’s inspiration is Prof Liesl van As, Associate Professor from the Department of Zoology and Entomology. She is also completing her undergraduate Zoology modules to later complete her postgraduate studies in Zoology. “As a student, our lecturers don’t often realise it, but they shape us to aim higher in life.”

According to Charissa, Prof van As is a woman of pure brilliance who has aspects that every woman should aspire to: Beauty, intelligence and a drive to succeed. “I owe a vast majority of my success to her, because even though she may not realise it, her motivational attitude and success in life drove me to succeed in areas of my life.”
