"Regina Hagen, who grew up in Germany during the Cold War, became actively involved in the campaign to abolish nuclear weapons after hearing an inspirational speech by Joseph Rotblat, founder of the Pugwash movement for global nuclear disarmament and Nobel Peace Prize laureate. Hagen became a coordinator of INESAP, the International Network of Engineers and Scientists Against Proliferation, which she describes as an interface between the political, scientific and activist arenas. She is now the managing editor of the quarterly magazine ""Wissenschaft und Frieden"" (Peace and Science). Hagen attended the May 2012 NPT Preparatory Committee with a group of German university students learning about nuclear disarmament and the work of the UN. While in Vienna, she took time out to discuss a variety of topics including young people, the importance of the CTBT and the challenges to its entry into force.
