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.

University of the Free State’s newly-appointed nGAP
lecturers. From the left, Neo Mathinya,

The University of the Free State (UFS) was allocated six positions as part of the Department of Higher Education and Training (DHET) New Generation of Academics Programme (nGAP). Four candidates have filled positions in the Faculty of Health Sciences, Faculty of the Humanities and the Faculty of Natural and Agricultural Sciences – with two positions still vacant.

According to Minister of Higher Education and Training, Dr Blade Nzimande, nGAP is part of the Staffing South Africa's Universities Framework, which focuses on the expansion of the size and compilation of academic staff at South African universities, especially with regard to transformation. The focus of the programme is the appointment of black and coloured candidates as well as women.

The Department of Soil, Crop, and Climate Sciences in the Faculty of Natural and Agricultural Sciences welcomed two nGAP lecturers, Phumudzo Tharaga and Neo Mathinya. The Faculty was allocated four positions. Two positions are filled, while two positions in the Department of Animal and Wildlife Sciences are almost ready to be filled with exceptional candidates.

Agrometeorologist with his feet on the ground
Phumudzo Tharaga holds an MSc from the UFS, and is currently pursuing a PhD. Tharaga’s research focuses on quantifying the water use efficiency of sweet cherry orchards under different climate conditions in the Eastern Free State. Tharaga will offer his students a wealth of practical experience, which he began accumulating while working at ABSA as an agro-meteorologist, before moving on to become a senior scientist at the South African Weather Service. In 2015, Tharaga became a research technologist at the Council for Scientific and Industrial Research (CSIR) and then returned to the UFS as an nGAP candidate at the beginning of 2016.

Motivated scholar turned academic
Neo Mathinya, who hails from Taung in the North West, has made the UFS her home. She received both her undergraduate and honours degrees from the university. Apart from joining the department as a lecturer under the nGAP initiative, she is currently studying for her MSc in Soil Physics. She will continue with this research when she comes to her PhD. Mathinya’s research focuses on soil salinity - the process of increasing salt content - which affects the ability of plants to take up water, a process, known as osmotic stress. She will investigate the effects of irrigation water salinity on the grain yield and quality of malt barley.

Researcher with a passion for crime prevention
Kelebogile Boleu joined the Department of Criminology in the Faculty of Humanities, with a fresh take on diversion and crime prevention. Boleu holds a BA Criminology (Hons) and is now pursuing her Master’s degree. She worked for NICRO a non-profit organisation specialising in social crime prevention and offender reintegration, with programmes that prevent young and first-time offenders from re-offending, thus reducing crime. Boleu said that her practical experience makes her lectures to third-year criminology students exciting. Boleu’s research focuses on analysing the value of pre-sentencing reports in assisting adjudicators to make well-balanced judgments in cases.   

Research with a winning plan for fight against breast cancer
Beynon Abrahams joined the Department of Basic Medical Sciences in the Faculty of Health Sciences. Abrahams holds a BSc, BSc (Hons), and MSc in Medical Biosciences from the University of the Western Cape. Abrahams’ Master’s research focused on breast cancer, research on which he is building in his PhD. This doctoral research involves the exploration of P-glycoprotein, a protein expressed on cancer cell and responsible for multi-drug resistance in cancer treatment. The aim of this research is to develop a therapeutic drug treatment strategy that will improve breast cancer patient survival outcomes. Abrahams’s greater vision is to look at conventional cancer therapeutic regimens, to find ways in which they can be improved.

The nGAP initiative offers these young lecturers an opportunity for growth and development as academics, while providing them with opportunities they would have not have been exposed to otherwise.
