In 1982, he became Chairman of the Geological Engineering Program at Waterloo and was Director of the Porous Media Research Institute from 1995 to 2000. Maurice carries out research in petroleum geomechanics (drilling, hydraulic fracturing, reservoir geomechanics…), and is the recognized world expert in new production methods, deep waste sequestration in sedimentary basins, and reservoir geomechanics. He has co-authored two textbooks, over 470 conferences and journal articles, and works with industry as an advisor and instructor. Dr Dusseault was a SPE Distinguished Lecturer in the year 2002-2003, visiting 19 different countries and speaking about new oil production technologies to 28 separate SPE Sections.
