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.

'Structures of Dominion and Democracy' by David Goldblatt at the Johannes Stegmann Art Gallery
2015-08-03

Photograph by David Goldblatt, On August 16 2012 South African Police shot striking mineworkers of the Lonmin platinum mines, killing 34 and wounding 78 within a radius of 350 metres of this koppie, where the men used to meet. Seventeen of the men, seeking shelter among boulders from police fire, were shot with seemingly lethal intent, some with their hands up in surrender, none were given medical assistance for their wounds. Beyond is the Lonmin smelter, which stood idle during the strike. Marikana, North-West Province, 11 May 2014.

The University of the Free State, in partnership with the Goodman Gallery, presents the exhibition, 'Structures of Dominion and Democracy', by renowned South African photographer David Goldblatt.  

This exhibition, which runs from 13 July to 7 August 2015 on the Bloemfontein Campus, is dedicated to the series, “Structures”, one of the major bodies of works by Goldblatt.  For over three decades, Goldblatt has travelled South Africa, photographing sites and structures weighted with historical narrative: monuments, private, religious and secular, which reveal something about the people who built them.  These sites allow us a glimpse into the everyday. Each place is a repository, a landscape containing an epic story that has involved whole communities: the experience sometimes told through the memorialising of remarkable individuals.

The exhibition, Structures of Dominion and Democracy, traverses two distinct eras in South Africa history. As Goldblatt explains: "Over the years, I have photographed South African structures, which I found eloquent, of the dominion which Whites gradually came to exert over all of South Africa and its peoples.  That time of domination began in 1660 when Jan van Riebeeck ordered a cordon to be erected of blockhouses and barriers that would exclude the indigenous population from access to the first European settlement in South Africa and its herds, lands, water, and grazing.  The time of domination ended on the 2nd of February 1990, when, on behalf of the government and the Whites of South Africa, President FW de Klerk effectively abdicated from power.  Beginning in 1999 and continuing to the present, I have photographed some structures that are eloquent of our still nascent democracy.  In the belief that, in what we build we express much about what we value, I have looked at South African structures as declarations of our value systems, our ethos.”
