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.

‘Captivating, powerful’ exhibition debuts at UFS
2016-08-29

Sue Williamson, What is this thing called freedom?, 2016 (two-channel video, 19min 25s)

A new exhibition by internationally-recognised artist, Sue Williamson, entitled No More Fairytales, was launched in the Johannes Stegmann Gallery on the Bloemfontein Campus of the University of the Free State (UFS) on 18 August 2016. The exhibition takes the audience on an exploration into the long-term effects of South Africa’s violent past.

No More Fairytales features two new video works. In It’s a pleasure to meet you, Candice Mama and Siyah Mgoduka—whose fathers were killed by Eugene de Kock—talk about living with loss, holding, on, and letting go. The other video, What is this thing called freedom?, draws the audience into a conversation between three generations of women in the Siwani family, who talk about the humiliations of apartheid, student unrest in the 1980s, and the recent #FeesMustFall protests.

“It’s all about opening up conversations.”

Both of these works have already been invited to participate in international exhibitions, the first of which, Un Autre Continent, opens in Le Havre, France, in September 2016. The videos will appear in 2017 in Without Drums and Trumpets—100 Years of War, also in France. The exhibition will run until 16 September 2016 at the UFS.

Sue Williamson, It's a pleasure to meet you, 2016 (two-channel video, 25min)

“There is such an energy to this large piece of work; there is something captivating, something powerful about its vibrancy,” said Prof Pumla Gobodo-Madikizela, Senior Research Professor in Trauma, Forgiveness and Reconciliation Studies at the UFS. The series was commissioned by Prof Gobodo-Madikizela as part of the project, ‘Trauma, Memory and Representations of the Past: Transforming Scholarship in the Humanities and the Arts’. The five-year research project is funded by the Andrew W. Mellon Foundation through a grant of R10 million.

The launch of the exhibition was followed the next morning by an insightful dialogue session between Prof Gobodo-Madikizela, Mama, Mgoduka, Williamson, and the audience. “It’s all about opening up conversations and trying to bring out things that have been so painful and so hurtful in this country,” Williamson said.
