Written by Pamela - I met Tim at Tuttle in 2009 or 2010. I followed his blog. We reconnected in 2011 when he was working with AidInfo to support the development of tools and ideas for working with International Aid Transparency Initiative data (www.aidtransparency.net) through http://www.aidinfolabs.org . He wanted help in connecting with realities on the ground.
Best way to find out more about him is to read his blog.
