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.

Number of NRF-rated researchers increases in 2012
2012-10-29

29 October 2012

Three researchers at the University of the Free State received B-ratings for 2013 from the National Research Foundation (NRF). Prof. Johan Henning, Dean of Law, obtained the highest rating in his field of mercantile law in South Africa, a B1.

Prof. Jackie Naudé from Classical and Near Eastern Studies and Prof. Dingie Janse van Rensburg, Professor Extraordinary at the Centre for Health Systems Research and Development, also obtained B3-ratings. Prof. Naudé is the first B-rated researcher in the Faculty of Humanities.
Prof. Helene Strauss obtained the highest rating (Y1) for a UFS young scholar in the Humanities.
In total, the NRF rated researchers at the UFS grew from 95 in 2011 to 109 in 2012, a growth of almost 15 percent.
The NRF ratings committee consist of three reviewers from South Africa and three from abroad. A rating is valid for six years and researchers must reapply for rating before the end of that period.
For a B1-rating all reviewers must be firmly convinced that the applicant enjoys considerable international recognition for the high quality of the researcher’s recent output, with some indicating that the researcher is a leading international scholar in a field. For a B3-rating most of the reviewers must be convinced that the researcher enjoys international recognition for the high quality and impact of the research.
Prof. Jonathan Jansen, Vice-Chancellor and Rector, said in the UFS Research Report “The UFS now has among the highest number of NRF-rated scientists per size of the academic faculty and we have seen the productivity graph bear witness to a record growth in our funded research outputs; we have won our first-ever NRF/DST Research Chairs. In each of these achievements, the excellence we seek comes with and through the diversity we celebrate.”
More ratings and renewals were expected by the time of Bult went to print.. More than 35 researchers applied for ratings or renewal of ratings.
  • Colleagues who were admitted to the prestigious Academy of Science of South Africa (ASSAf) are Profs. Pumla Gobodo-Madikizela, Driekie Hay, Heidi Hudson, Lodewyk Kock, Odireleng Ntwaeaborwa, Hugh Patterton, Ian Phimister and Melanie Walker. ASSAf was established in 1996 with the mission of using science for the benefit of society. New members are elected after nomination by four existing members (at least two of whom do so from personal knowledge of the candidate). ASSAf has some 350 members and represents South Africa in the international community of science academies.
  • Dr Marieka Gryzenhout of Plant Sciences became a member of South African Young Academy of Science (SAYAS). SAYAS celebrated its first year in 2012. It was launched as a means to enable South Africa’s young scientists to fully participate in locally and internationally relevant research and development agendas. Prof. Aldo Stroebel, Director: Internationalisation, is also a member of SAYAS.
