Richard Loulou joined the Faculty of Management in 1970 and has been Associate Dean Academic since 1993. In 1980, he co-founded the Groupe d'Étude et de Recherches en Analyse des Décisions (GÉRAD), and served as its Director from 1988 to 1992. GÉRAD is a joint research centre of McGill, École des Hautes Études Commerciales (Montréal), and École Polytechnique (Montréal). Dr. Loulou has taught such undergraduate and graduate courses as Applied Optimization, Simulation, Stochastic Processes and Operations Research. He has been a Visiting Professor and Researcher at Université de Sherbrooke and Université de Grenoble, France, during the period of his association with McGill.

Richard Loulou's research focusses on the modeling and analysis of energy/environment systems. His current projects involve the development of mathematical and economic models of large scale energy systems and their use for the investigation of numerous issues related to energy and the environment, with special emphasis on the abatement of greenhouse gas emissions. In association with Dr Amit Kanudia, Richard Loulou leads a team of researchers which continuously develops, maintains, and enhances the MARKAL techno-economic model, and its application to Canada, the USA, and several other regions of the World. The current phase of the MARKAL project invloves the creation of a World-Wide model based on multi-regional models linked via energy and GHG permit trade variables. This new model is named TIMES (The Integrated Markal-Efom System), and represents the next generation of model created by ETSAP and destined to replace the existing versions of MARKAL and EFOM. This work is done in collaboration with, and with the sponsorship of the Energy Technology Systems Analysis Programme, an implementing agreement of the International Energy Agency.

Another major current project concerns the use of the 7-region Canadian MARKAL model to analyze alternate paths to satisfy Canada's GHG abatement target under the Kyoto Protocol. This project is undertaken in direct collaboration with the Third Assessment Report of the Intergovernmental Panel on Climate Change.

Throughout his academic career Dr. Loulou has maintained a close association with the business community, involving contractual research with private and public organizations such as Natural Resources Canada, Environment Canada, Hydro-Québec, BC Hydro, GCSI Inc., Northern Telecom, Montréal Children's Hospital and Québec Cartier Mining. Formerly Associate Editor for INFOR and for INTERFACES, he has also contributed to the profession as an evaluator for grants, scholarships and proposals for Conseil des Universités, FCAR and NSERC.

Dr. Jean-Louis Goffin joined McGill's Faculty of Management in 1976. He had previously been an Assistant Professor at l'École des Hautes Études Commerciales in Montreal.

Dr. Goffin teaches undergraduate and graduate courses, including Operations Research, Applied Optimization, Simulation of Management Systems, Data Models and Decisions, and Operations Management.

The extension of interior point methods to the context of column generation and cutting plane methods has led to a very competitive new methodology for large scale optimization, the Analytic Center Cutting Plane Method (ACCPM). A computer code has been developed with LOGILAB and has been applied to the solution of linear or nonlinear network design problems, of multi-item inventory problems with setup costs and times, and to the computation of economic equilibria.

Dr. Goffin's work has appeared in such journals as Management Science, Mathematical Programming, Mathematics of Operations Research, Contemporary Accounting Research, SIAM Journal on Optimization, Discrete Applied Mathematics, European Journal of Operations Research, Operations Research Letters, Linear Algebra and its Applications, Computational Optimization and Applications, Mathematical Methods of Operations Research, and Journal of Optimization Theory and Applications. He has also delivered more than forty lectures or seminars in the last five years at a variety of prestigious Universities, or Conferences.

He has been awarded numerous research grants, including more than twenty-five years of funding by both FCAR and NSERC.

In 1980, Dr. Goffin co-founded the Groupe d'Études et de Recherches en Analyse des Décisions GÉRAD, a Montreal-based inter-university research center. In 1980/81, he was a Visiting Scholar with the Department of Operations Research at Stanford University and in 1987/88, a Visiting Professor at the Center for Operations Research and Econometrics at the Université Catholique de Louvain. He is also an associate member of the Department of Mathematics at McGill, and LOGILAB, HEC, University of Geneva.

Dr. Goffin has made significant contributions to a number of associations in his field. He co-directed the International Symposium on Mathematical Programming in 1979. He sits on the Editorial Board of Computational Optimization and Applications, and was Guest Editor for special issues of the Mathematical Programming Journal of Studies.
