In Engines of Innovation, Holden Thorp and Buck Goldstein make the case for the pivotal role of research universities as agents of societal change. They argue that universities must use their vast intellectual and financial resources to confront global challenges such as climate change, extreme poverty, childhood diseases, and an impending worldwide shortage of clean water. Combining their own experiences cultivating an entrepreneurial mindset within one of the nation's elite public universities with detailed descriptions of the approaches taken by others, Thorp and Goldstein provide not only an urgent call to action but also a practical guide for our nation's leading institutions to become major players in solving the world's biggest problems. The result is a provocative and thoughtful beginning to an important conversation among educators, their supporters and trustees, policymakers, and the public at large as to how the American research university can best meet its societal responsibilities.
