Andy Carvin (andycarvin.com, @acarvin on Twitter) leads NPR's social media strategy and is NPR's primary voice on Twitter, and Facebook, where NPR became the first news organization to reach one million fans. He also advises NPR staff on how to better engage the NPR audience in editorial activities in order to further the quality and diversity of NPR's journalism.

During his time at NPR, Carvin has been interviewed on numerous NPR programs, including Morning Edition, All Things Considered, Talk of the Nation, Tell Me More and The Diane Rehm Show, as an expert on Internet policy and culture and related topics.

As co-founder of PublicMediaCamp, Carvin has helped NPR and PBS stations around the country bring local tech communities and public media fans together to develop collaborative projects both online and offline.

Prior to coming to NPR in 2006, Carvin was the director and editor of the Digital Divide Network, an online community of educators, community activists, policymakers and business leaders working to bridge the digital divide. For three years, Carvin blogged about the impact of the internet culture on education at the PBS blog learning.now.

During natural disasters and other crises, Carvin has used his social integration skills to mobilize online volunteers. On September 11, 2001, he created SEPT11INFO, a news forum for the public to share information and help refute rumors in the wake of the 9

11 attacks. Following the tsunami off the coast of Indonesia in 2004, Carvin served as a contributing editor to TsunamiHelp, one of the leading sources of tsunami-related citizen journalism. More recently, he worked with CrisisCommons, to help with their development of shared technology solutions to improve emergency management and humanitarian activities in response to the 2010 earthquake in Haiti.

In 1994, Carvin created the pioneering online education resource EdWeb: Exploring Technology and School Reform, one of the first websites to the impact of telecommunications policy on education. Carvin is the founder and moderator of WWWEDU, the Internet's oldest and largest email forum on the role of the Web in education.

Well known as a leader in technology and innovation, Carvin was named by Washingtonian magazine as one of the 100 leading technology innovators in Washington, D.C., in 2009. In 2005, MIT Technology Review magazine included Carvin on TR35, an annual list of 35 of the world's leading high-tech innovators under the age of 35. The District Administration magazine named him as one of America's top 25 education technology advocates in 2001. Carvin received similar honors from eSchoolNews in 1999 when they named him a member of its Impact 30 list of education technology leaders.

After graduating with a bachelor of science in rhetoric and a master of arts in telecommunications policy from Northwestern University, Carvin received the prestigious Annenberg/Washington postgraduate policy fellowship.
