The work of Louis-A. Dessaint in the field of electrical systems simulation and command has earned him an international reputation. His work has produced major benefits and is quoted in close to 40 international publications. It also has led to the development of an electrical systems simulation software package largely used all over the world, primarily in universities. Finally, as holder of the Hydro-Québec/TransEnergy Chair, Louis-A. Dessaint has created a hive of new talents in electrical energy engineering, in order to produce strong and dynamic future replacements for the Canadian electrical industry.
