Hi Ashlee,
Will you consider a master's program? I know Ohio University has a Communication and Development (Commdev) program under the Center for International Studies ( http://www.commdev.ohio.edu/ ). You could probably pursue a PhD in Comm at Scripps and take some development-focused courses offered by the Center.
I hope this helps. I'm also eyeing the CommDev program, even though I already have a master's.
