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.

The 31st Congress of the International Limnological Society (SIL) was recently held at the Cape Town International Convention Centre (CTICC).

Prof. Johan Grobbelaar from the Department of Plant Sciences at the University of the Free State (UFS), who is also the chairperson of the local organising committee (LOC), worked hard for six years to secure the bid to host the congress in South Africa. The LOC consisted of Prof. Grobbelaar, Prof. Brian Allanson, Prof. Jenny Day, Dr Carin van Ginkel and Dr Mike Silberbauer.

SIL was founded in 1922 to further the study and understanding of all aspects of limnology, the science of inland aquatic ecosystems and their management.

Congresses are held every three years and this was the first time that SIL met on the African continent.

Almost 400 delegates from 42 countries attended this congress where the state of the science of limnology was presented with two keynote speakers, six plenary lectures, 230 oral and 76 poster presentations, mostly running in five parallel sessions. Exhibitions displayed some of South Africa’s role players as well as the latest equipment from abroad. Delegates could also join pre- and post-congress excursions and the new SIL journal, Inland Waters, was launched at the congress.

Many of the presentations dealt with water as a limited resource, pollution problems and the impact of climate change. The congress resolved that SIL would play a more prominent role in creating awareness of problems impacting on inland waters and also afforded solutions. The 32nd SIL congress will be held in Budapest, Hungary in 2013.
