of junior personnel, analysis, design and implementation of the interfaces as well as the databases, as well as deployment and maintenance of system. After our second daughter was born, I decided to investigate a career as academic. I went to Unisa as a senior lecturer in several subjects and completed a Ph. D. degree in Semantic Web technologies (2007).  During that time I joined the IEEE, and with one of my Ph. D.  supervisors, Professor Alta van der Merwe, we established the IEEE SMCS Chapter in South Africa. I enjoyed academia and research and when the CSIR decided to place more emphasis on research excellence, I joined CSIR again for the third time. I helped with the formulation of research strategies for some of the core groups, as we created our group in Knowledge Representation and Reasoning at the CSIR, as well as the Centre for Artificial Intelligence Research (CAIR - see http://www.cair.za.net/). At present I am principal researcher in knowledge representation and reasoning at CSIR, as well as in CAIR. I am also chair of the IEEE SMCS chapter in South Africa. I find ontologies and modeling interesting, and my research focuses on the development and application of models, specifically formal ontologies using DLs (Description Logics). In addition, my years as system developer and technical project leader, as well as my research colleagues lead to an interest in software and systems architectures and software engineering. This interest grew to a additional research focus in enterprise architectures and enterprise engineering
