RESEARCH INTERESTS: The main focus at present is on the use of Operations Research techniques for the sustainable utilisation of African wildlife, particularly on game ranches. Other current research projects include the determination of optimal cattle management strategies for semi-arid regions, the biological control of the sugarcane pest, Eldana saccharina, and determining freshwater requirements for estuaries.

CURRENT ACTIVITIES: Contributing Editor of International Abstracts in Operations Research; Associate Editor of ORiON; Member of the Editorial Board for Ecological Modelling; Executive Secretary of the Resource Modeling Association.

PAST ACTIVITIES: President (1997-1999) of the Operations Research Society of South Africa; President (1999-2000) of the Resource Modeling Association.
