This paper addresses the role of engineering PhD education and its relationship to innovation and technology, and the need to reconsider how we educate PhD engineers. Much of the effort on engineering education in the last two decades focused on undergraduate education with a few exceptions that relate to master degree programs. Doctoral education in engineering prepares the next generation faculty, researchers, and technology leaders and warrants our attention. Whilst current education has been largely responsible for technological advances, there is a need for a new model of engineering PhD education that prepares renaissance engineers. This paper focuses on the doctoral education and its role in the USA; however, the issues addressed are universal among the countries that offer PhD degrees in engineering.
