Masih worked in Iran for more than ten years, covering the Majlis (Parliament) for Hambastegi newspaper and later as a columnist for Etemaad Melli. After being forced to leave Iran in 2009 due to her bold reporting, Masih continued her activism abroad. She produced a multi-award-winning radio series on the victims of the 2009 crackdown against those protesting the disputed presidential elections. Currently, she reports and presents a weekly TV segment on VOA called Tablet, where she skillfully combines hard news with satire. In 2014, Masih created the My Stealthy Freedom movement through a Facebook campaign, which now has around 1 million followers. The MSF movement is the largest women's campaign in Iran, empowering women to share photos of themselves without hijabs in protest of the country's strict dress codes. Masih and My Stealthy Freedom have been covered by more than 100 media organizations globally, including Vogue, Reuters, The Guardian, The New York Times, Le Monde, La Repubblica, and Der Spiegel. In February, the Geneva Summit for Human Rights and Democracy awarded Masih their Women’s Rights Award for “giving a voice to the voiceless and stirring the conscience of humanity to support the struggle of Iranian women for basic human rights, freedom, and equality.” Her writings have been published in numerous newspapers and magazines, including the Huffington Post, Time Magazine and the Washington Post.
