John Goldak is the Founder and President of Goldak Technologies Inc. GTI), a company dedicated to developing software for design-driven analysis and optimization of welded structures. GTI was awarded the John S. Hewitt Team Achievement Award by the Canadian Nuclear Society in 2011as a major player for its computational weld mechanics analysis that contributed to the successful repair of AECL's NRU reactor in 2009. GTI has done and does work with leading multinationals in the agricultural machinery industry; for the Canadian Navy on computational mechanics for weld repair of submarines and for leading organizations in the Canadian and USA nuclear power industry.

John Goldak is Distinguished Research Professor and Lifetime Emeritus Professor at Carleton University. He has been at Carleton University since 1965. He has a Ph.D. in Physical Metallurgy from the University of Alberta. From 1993 to 1997, he held the NSERC-MRCO Industrial Research Chair in High Pressure Die Casting. Internationally he is best known for his research in the computational mechanics of welds. In particular for the development of a heat source model for arc welds that is widely known as the Double Ellipsoid Weld Pool Model. In 2011, The Welding Science and Engineering Conference created the `The Pioneers of Computational Weld Mechanics' award to honor the contributions of Professor Yukio Ueda, Osaka, Japan and John Goldak to the develop- ment of computational weld mechanics. The American Welding Society has awarded him the Comfort A. Adams award for 2014. He is a member of the Canadian Academy of Engineering.
