Stephen Mulkey is an environmental scientist dedicated to developing undergraduate and graduate programming to build society's capacity for environmental mitigation, adaptation, and resilience. Mulkey was the president of Unity College in Unity, Maine from 2011 through 2015. 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 spent over twenty years as a forest ecologist affiliated with the Smithsonian. Mulkey has served as tenured faculty at three research-one universities.
