Beginning in September 2012, I am an Assistant Professor in the School of Media and Public Affairs at George Washington University.  I previously spent two years as an Assistant Professor at Rutgers University’s School of Communication and Information.  My research explores the internet’s impact on political associations —  both in the formation of novel organizational structures seen in MoveOn and DailyKos, and also tracing implications for more traditional advocacy organizations.  My first book, The MoveOn Effect: The Unexpected Transformation of American Political Advocacy was published in May 2012 by Oxford University Press.

This site is home to all my working papers and publications.  I also offer links to my two public datasets — the Blogosphere Authority Index and the Membership Communications Project.

Previous academic positions have included a visiting fellowship with the Yale Information Society Project, a postdoctoral position at Brown University’s Taubman Center for Public Policy and a predoctoral fellowship at the University of Virginia’s Miller Center for Public Affairs.  I earned my Ph.D. in political science from the University of Pennsylvania in 2009 and my B.A. in Politics from Oberlin College in 2002.

In addition to my academic portfolio, I am a longtime volunteer leader with the Sierra Club.  I have been a member of that organization since 1995, served as National Director of their student-run arm in 1999, and served on their national Board of Directors from 2004-2010.
