Stephen Mulkey is the president of Unity College in Unity, Maine. His leadership and forward-looking vision resulted in Unity College being the first college in the U.S. to divest its endowment from the top 200 fossil fuel companies, and the first college in the U.S. to adopt sustainability science as the framework for all academic programming. Mulkey believes that higher education has an ethical duty to prepare generations of graduates for the extreme sustainability and climate change challenges of this century. After taking his PhD at the University of Pennsylvania, he has spent most of his career as a forest ecologist affiliated with the Smithsonian and as tenured faculty at three research-one universities. Mulkey has dedicated recent years of his career to developing undergraduate and graduate programming to build society's capacity for environmental mitigation, adaptation, and resilience.
