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.

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

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.

The District Administration magazine named him as one of America's top 25 education technology advocates in 2001.
