Godfried T. Toussaint received the B.Sc. degree from the University of Tulsa, in Tulsa, Oklahoma, U.S.A. and the M.A.Sc. and Ph.D. degrees from the University of British Columbia, Vancouver, B.C., Canada in 1968, 1970, and 1972, respectively, all in Electrical Engineering.

Since 1972 he has been teaching and doing research in the Department of Computer Science at McGill University in the areas of information theory, pattern recognition, and computational geometry. During the summers of 1975 and 1977 he was a Visiting Scholar at the Information Systems Laboratory, Stanford University. The sabbatical year 1980-81 he spent as a Visiting Scientist at the Applied Mathematics Research Center of the University of Montreal. During the spring of 1986 he was a Visiting Scholar at the Courant Institute of Mathematical Sciences, NYU. During the fall of 1988 he was a British Columbia Advanced Systems Institute Fellow at Simon Fraser University. In the spring of 1989 he was a Visiting Professor in the Mathematics Department at the University of West Indies, Cave Hill, Barbados, and during the summer of 1989 he was a Visiting Scientist in the Department of Mathematics and Computer Science at the University of Amsterdam. He spent the sabbatical year 1995-96 in Australia and Spain. In the fall of 1995 he was a Vice-Chancellor's Research Best Practice Fellow at the University of Newcastle. In the spring and summer of 1996 he held Visiting Professor appointments in the Departments of Applied Mathematics at the Universidad Politecnica de Madrid and the Universidad Politecnica de Catalunya in Madrid and Barcelona, respectively.

Dr. Toussaint is past council-member of the North American Branch of the Classification Society, past Associate Editor of Pattern Recognition, past Associate Editor of the IEEE Transactions on Information Theory and of the IEEE Transactions on Pattern Analysis and Machine Intelligence. Presently, he is Associate Editor of Computational Geometry:Theory and Applications, Associate Editor of the International Journal of Computational Geometry and Applications and Associate Editor of The Visual Computer. He is also on the Editorial Boards of of the journals Discrete & Computational Geometry and Forma as well as on the Advisory Board of the IEEE Transactions on Pattern Analysis and Machine Intelligence. He is a member of several learned societies including the Pattern Recognition Society and the New York Academy of Sciences. He recently edited two books published by North Holland, Computational Geometry in 1985 and Computational Morphology in 1988. He has also served as a guest editor for four journal special issues on computational geometry: The Visual Computer (the May issue of 1988 and issue No. 8 of 1994), The Proceedings of the IEEE (September 1992) and Pattern Recognition Letters (September 1993). In 1978 he was the recipient of the Pattern Recognition Society's Best Paper of the Year Award and in 1985 he was awarded a Killam Fellowship by the Canada Council to carry out a two- year research project on movable separability of sets. In 1996 he was awarded the Canadian Image Processing and Pattern Recognition Society's Service Award for his outstanding contribution to research and education in Computational Geometry.
