In October, twenty faculty fellows representing a wide cross-section of expertise and experience came together to launch our fourth year of the Public Voices Fellowship at Northwestern University. Since that day, the 2015-16 Northwestern Public Voices Fellows have convened in person and virtually to test ideas about knowledge, public impact, and what it takes to be influential on a large scale. They endeavored to test the best existing research, learn from live experiments, tackle big philosophical questions and create an environment that is wildly generative of ideas. In doing so, the 2015-16 Northwestern Public Voices Fellows have become our most productive cohort to date, producing 141 concrete examples of thought leadership. See their photos below.
