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.

A model of resilience – Dr Anja Botha probes into the ability to recover from trauma
2014-12-02

She may have been awarded her doctorate degree only in July 2014, but Psychology lecturer at the University of the Free State (UFS), Dr Anja Botha, is already making a name for herself with her latest research.

Her study aims to develop a model of resilience for South African adolescents exposed to trauma. “The broad field, within which I work, is that of Developmental Psychology, with a specific focus on child and adolescent development and therapy,” says Dr Botha. 

Resilience studies are situated within Developmental Psychology since normal developmental tasks – such as achieving self-confidence and building supportive relationships – contribute greatly to children’s resilience. Resilience broadly refers to the individual’s ability to ‘bounce back’ after being exposed to adversity.

“The model of resilience which I compiled was a good fit for my participant group, indicating that the model explains the development of resilience in these adolescents well. The factors that I found to promote resilience in the South African context include various coping skills, intra- and interpersonal strengths, family involvement, and school engagement.

“Thus, aside from my passion for resilience studies, I am also very much interested in coping, strength-based interventions, parental guidance and school-based programmes.”

Dr Botha was awarded a Donald J Cohen fellowship in August 2014 during the 21st World Congress of the International Association for Child and Adolescent Psychiatrists and Allied Professions. The fellowship is in recognition of her work as an emerging international scholar in the field of child and adolescent mental health. This award was based on both her research as well as her involvement in the training of postgraduate students in child psychology.

She is currently supervising a number of master’s students’ research on various constructs related to resilience.
