Recently retired, Murray spent his entire career at Praxair and its former parent company, Union Carbide. Following college in 1981, he joined Union Carbide Plastics and Chemicals in Sarnia, Ontario, Canada as a project engineer. After assignments in plant operations and new product production at that facility, he transferred to the gases division in Toronto. This eventually became Praxair Inc. and Murray held assignments in operations, maintenance, plant operations, facilities planning, and sales before becoming Managing Director for Canada in 1999. In 2002, he transferred to the Tonawanda, New York technical center to assume responsibility for North American industrial gas operations. His next assignment in 2005 was President of Praxair Asia, based in Shanghai, China with accountability for the South Korea, China, Thailand, and India regions. He returned to the United States in 2009, again based in Tonawanda, to lead the global operations and procurement groups and, subsequently, to lead the Global Supply Systems (GSS) group that was responsible for the development, design, project management, and construction of the non-hydrogen facilities for Praxair. Murray held this role from 2010 to 2015 until his retirement.
Murray received a BASc in Mechanical Engineering from the University of Toronto and an MBA from York University (Toronto).
