Michael A. Henning is a world-leader in domination theory in graphs. He has been a plenary and invited speaker at several international conferences and is a prolific researcher having published over 460 papers to date in international mathematics journals. Michael was born and schooled in South Africa having obtained his PhD at the University of Natal in April 1989. In January 1989, he started his academic career as a lecturer at the University of Zululand, before accepting a lectureship in mathematics at the former University of Natal in January 1991. In January 2000 Michael was appointed a Full Professor at the University of Natal, which later merged with the University of Durban-Westville to form the University of KwaZulu-Natal in January 2004. After spending almost 20 years at the University of KwaZulu-Natal and one of its predecessors, the University of Natal, Michael moved to the University of Johannesburg in May 2010 as a research professor. ​Anders Yeo is a world-leader in several areas within mathematics and computer science, including total domination in graphs and transversal in hypergraphs, digraphs and algorithms. He has been a plenary and invited speaker at several international conferences and is a prolific researcher having published over 150 papers to date in international mathematics journals. Anders was born in Australia and schooled in Denmark having obtained his PhD at Odense University in December 1997.  Thereafter Anders has worked at the University of Victoria in Canada, the University of Aarhus in Denmark, Royal Holloway, University of London, in the UK, the University of Johannesburg in South Africa and the Singapore University of Technology and Design in Singapore.  Currently Anders is a professor of Mathematics at the University of Southern Denmark in Denmark.
