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.

Professor Johan Grobbelaar, from the Department of Plant Sciences at the University of the Free State, has been invited by the Institute of Bio- and Geosciences - IBG-2 at Forschungszentrum Jülich GmbH - to do research in Germany from 8 June 2015 to 4 September 2015.

During his research, Prof Grobbelaar will work on the institute’s large-scale outdoor cultivation of green micro-algae with the aim of finding alternate fuels for the aviation industry. This work includes the cultivation of algae in the laboratory, outdoors, and in the greenhouse; the mentoring of local scientists as well as assistance in, and planning of experiments for, green algae cultivation.

Prof Grobbelaar’s research focus is on Algal biotechnology, Limnology, and Photosynthesis. He has authored more than 80 articles in scientific journals, 18 chapters in scientific books, delivered more than 120 papers at scientific meetings, 41 of them at international congresses.  Among others, he was honoured with the highest award bestowed on a person by the International Association of Applied Phycologists with the title ‘Distinguished Applied Phycologist’.
