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.

PhD students’ voices reverberate across Africa and beyond

The Centre of Africa Studies (CAS) has been recruiting the best young scholars from across the SADC region – with magnificent success. In the span of six months, four PhD students have excelled both on the African continent and abroad.

Anusa Daimon, Noel Ndumeya, Ivo Mhike and Tinashe Nyamunda – the names of these distinguished students. Set against the backdrop of global excellence and competition, they have been awarded several positions at conferences and already published world-wide.

Anusa Daimon’s PhD studies at the CAS focuses on Malawian migrants and their descendants in Southern Africa. It explores issues of identity construction and agency among this group.

Since his arrival at the CAS, Daimon has won two fully-funded awards to attend international conferences and workshops. He was invited to attend the Young African Scholars Conference at Cambridge University in the UK. He also went to Brazil to the IGK Work and Human Lifecycle in Global History Summer Academy. This workshop explored the historical and modern meanings and practices of work in terms of ‘freedom’ and ‘unfreedom’.

Noel Ndumeya holds a special interest in environmental history and the aspects of conservation and conflict. His PhD hones in on land and agrarian studies with specific focus on South Eastern Zimbabwe.

Ndumeya has won an award from the African Studies Association United Kingdom (ASAUK). This earned him an invitation to Nairobi, Kenya, to work with an editor from the Journal of Southern Africa Studies (JSAS).

Ivo Mhike’s research specialises in youth culture and their relationship with the state. In his PhD he uses juvenile delinquency as a window towards an analysis of social constructs of youth behaviour. This includes youth policy and their institutional and administrative links to the state.

Mhike has been invited to attend the CODESRIA Child and Youth Institute in Dakar, Senegal, with the theme: Social Protection and the Citizen Rights of Vulnerable Children in Africa.

Tinashe Nyamunda specialises in African Economic History. His PhD thesis is entitled, “The State and Finance in Rhodesia: A study of the evolution of the monetary system during the Unilateral Declaration of Independence (UDI), 1965–1979”.

Under the direction of his primary supervisor, Prof Ian Phimister and his secondary supervisor, Dr Andrew Cohen, four of his papers have been accepted for publication. Nyamunda also received sponsorship from the Rector’s Office for an edited book collection of which he is the leading author. The book focuses on the many aspects of Zimbabwe’s blood diamonds.

Recently, Nyamunda has contributed papers at conferences in Botswana and Scotland and attended a workshop at Lund University in Sweden. He has also received an invitation from Germany and Oxford to present some chapters of his PhD thesis.

“The centre has provided the best working environment any PhD student can dream of,” Nyamunda said. He continued to remark that the opportunities Prof Jonathan Jansen has created opened up immense possibilities for them.

“Given these fruitful experiences in just a year at the university,” Nyamunda said,” imagine what can be accomplished given the resources and environment availed by the institution.” The prospects after his PhD studies looks bright, he concluded, because of the opportunities provided by the UFS.
