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.

Acclaimed Polish author and academic Dr Eva Hoffman visited the University of the Free State’s (UFS) Bloemfontein Campus on 16 Augustus 2010 to deliver a lunch-time lecture on the subject of contested memories.

Speaking about the after-effects of unjust violence on second-generation Holocaust survivors, Dr Hoffman drew some parallels between the history of Eastern Europe and that of South Africa, stating that with some categories of conflict and prejudice the context in this region of the world might not be too remote. Dr Hoffman, born to Jewish parents who survived the Holocaust, told the audience that in most instances the past was still alive in the present.
 
Talking about traumatic memories, Dr Hoffman revisited her family’s suffering during the Holocaust and stated that the second generation lives with the paradoxes of indirect knowledge. According to her there has to be acknowledgment of the injustice to put the conflict and tension inherited from a repressed history truly to rest. Referring to the work of the Truth and Reconciliation Commission (TRC), she said wrongs could not be forgiven until they were admitted. 
 
Dr Hoffman, who is the author of books such as Lost in Translation: life in a new language and Stetl: the life and death of a small town and the world of Polish Jews, praised the university for being on the forefront of social issues in democratic South Africa.
