Worldwide, EMU is probably best known for its Center for Justice and Peacebuilding (CJP), especially its graduate program in conflict transformation. CJP has educated and trained more than 3,000 people from 124 countries. CJP's founding director, John Paul Lederach, and its expert in restorative justice, Howard Zehr, are considered to be international leaders in the fields of peace and justice. CJP alumna Leymah Gbowee was a co-recipient of the 2011 Nobel Peace Prize. In her autobiography, she speaks of EMU as "an American college with a well-known program in peace-building and conflict resolution" and with an emphasis on "community and service." President of Somalia Hassan Sheikh Mohamud is also an alumnus of Eastern Mennonite University's Summer Peacebuilding Institute based in Harrisonburg, Virginia. In 2001, he completed three of the SPI's intensive courses, studying mediation, trauma healing, and designing learner-centered trainings. He credits the tools and instruments that he acquired while attending the SPI with having equipped him with the necessary diplomatic skills to successfully engage challenging circumstances in his everyday work.
