Dr. Moselhi has a Ph.D., M.Eng., and B.Sc. in Civil Engineering. He has 30 years of professional experience working in the construction industry and in academic posts both in Canada and abroad. Dr. Moselhi specializes in construction engineering and management. He joined Concordia in 1985.

He has held several industrial and academic posts in Canada and abroad in a wide spectrum of the engineering profession, ranging from structural analysis and design to construction engineering and management, on building projects, and heavy civil engineering including bridges, offshore and harbor facilities, and nuclear power plants.

Dr. Moselhi is a Fellow of the Canadian Society for Civil Engineering and a fellow of the American Society of Civil Engineers. He is a member of the Engineering Institute of Canada, the the American Association of Cost Engineers (Directory and Past President of the Montreal Section), the Projects Management Institute, the International Association of Automation and Robotics in Construction (Director), Professional Engineers of Ontario, and the Order of Engineers of Quebec.

Dr Moselhi was elected Fellow of the Canadian Society for Civil Engineering (CSCE) in 1994 and the American Society of Civil Engineers in 1999. He has received several honors and awards including the CSCE Gzoowski's Gold Medal in 1979.
