She is the author of Cyberactivism and Citizen Journalism in Egypt: Digital Dissidence and Political Change and worked as the advocacy director for the Committee to Protect Journalists until 2021.
In her chapter on the blogosphere and social media in a study by the Stimson Center, Seismic Shift: Understanding Change in the Middle East she argues that between 2005 and 2010 Middle Eastern blogs and social media showed rising dissatisfaction with the status quo, declining levels of fear and visible capability to mobilize large political protests.
[11][12][13] In 2005, Radsch left the Times to pursue a Ph.D. in international relations at American University, where her research focused on cyberactivism in Egypt.
Her dissertation, Digital Dissidence and Political Change: Cyberactivism and Citizen Journalism in Egypt, provides the first scholarly examination of the development of the youth movement in Egypt and the role that technology played in reconfiguring what she calls "the potentiality for expression and participation" and thus contributes to understanding how ICTs are implicated in processes of political change.
In 2008, Radsch was hired by the Saudi-owned, Dubai-based Arabic satellite channel Al Arabiya as the English website managing editor.
