Michael 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 300 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 in Fixed Parameter Tractability. He has been a plenary and invited speaker at several international conferences and is a prolific researcher having published over 130 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 he pursued postdoctoral studies in the Department of Mathematics and Statistics at the University of Victoria in Canada for one year and postdoctoral studies in the Computer Science Department at the University of Aarhus in Denmark for a further two years. In September 2001 he began as a lecturer at Royal Holloway, University of London and was very rapidly promoted to Reader in March 2003 where he worked until January 2012. Anders is currently employed by the University of Johannesburgin a research capacity.
