Murphy worked in the Peace Corps and later as a public health officer in Zaire and Central America. She also was a foreign service officer and an aid contractor, gaining first hand experience of the mishandling of America's public policy.
In 2002 she helped coordinate Code Pink's Women’s Peace Vigil held across from the White House. She heads up the group’s D.C. office. She is also a member of its executive committee. A Salon writer who interviewed Murphy in 2008 described her as a "warmly robust, welcoming and intelligent presence with a firm handshake" who was tough enough for hard questioning.
At an antiwar protest rally during United States President Barack Obama's Inauguration where protesters threw shoes at a balloon replica of George W. Bush, Murphy told protesters ""Hold onto your shoes. The struggle is not over."
Ms. Murphy is among the activists featured in a recent anti-war documentary film, "Finding Our Voices."
