About Prof Dirk Opperman
Prof Dirk Opperman obtained his PhD in Biochemistry at the University of the Free State in 2008. This was followed by postdoctoral research on directed evolution with Prof Manfred T Reetz at the Max Planck Institute for Coal Research (Germany). In 2010, he was appointed in the Department of Microbiology and Biochemistry. He subsequently established structural biology at the UFS, and his current research focus lies at the interface of evolutionary and structure-function relationships of biocatalysts, and their application in green chemistry. He is an NRF B-rated researcher with co-authored papers in Science, Nature Communications, and Angewandte Chemie.
His research has been funded by both local and international organisations, ranging from industries such as SASOL to the Global Challenges Research Fund (GCRF, UK). He has a long-standing collaboration with researchers at the Delft University of Technology (TUDelft, the Netherlands) and is currently part of a European Research Area Network Cofund (ERA-NET Cofund) partnership on Food Systems and Climate (FOSC) that develops biocatalysts for upcycling waste.

“Having spent the most of my life in public service, it is a great pleasure to receive recognition from the University of the Free State (UFS) for the work that I have done,” Dr John Samuel said in his acceptance speech at this year’s Winter Graduation, where an honorary degree was conferred on him.
The renowned educationalist’s remarkable merit was recognised by the Faculty of Education in the Thursday 2 July 2015 graduation ceremony. Dr Samuel was awarded the honorary doctorate for his enormous role as a national and international strategist in the education system.
The early 1960s proved to be a prelude to Dr Samuel’s lifelong journey as a teacher, policy analyst, administrator, and advisor. In addition to South Africa, he has served with compassion in various countries including Zambia, Ghana, Nigeria, and the USA.
In the dawn of South Africa’s democracy, Dr Samuel served as Head of the Education desk, developing new policies for the field of education and training. One of his many pivotal achievements has been serving the Nelson Mandela Foundation as Chief Executive Officer. Furthermore, South African’s Department of Education has reaped the benefit of appointing him as the Deputy Director-General.
From 1998 to 2000, Dr Samuel was the Senior Programme Director of the WK Kellogg Foundation in the USA.
The Chief Executive Chairman of the Oprah Winfrey Leadership Academy for Girls inspired graduates with warm words. “Graduation is a special time for everyone. It is now the time to convert what we have learnt into useful action. We need every pair of hands to help and inspire, and instill hope,” he said.
Rewarding the active role of a national and global leader in education symbolises the university’s commitment to public service, academic excellence, and transformation.
