The creator of GrassrootsMapping.org and co-founder and Research Director for Public Lab, Jeffrey Warren designs mapping and civic science tools and professionally flies balloons and kites. Notable software he has created include the vector-mapping framework Cartagen and orthorectification tool MapKnitter, as well as open spectral database and toolkit Spectral Workbench.

He is Vice President of the board of the Open Source Hardware Association, on the board of alternative education program Parts and Crafts in Somerville MA, on the advisory board of Personal Democracy Media's WeGov and an advocate of open source software, hardware, and data. He co-founded Vestal Design, a graphic/interaction design firm in 2004, and directed the Cut&Paste Labs project, a year-long series of workshops on open source tools and web design in 2006-7 with Lima designer Diego Rotalde.

Jeff holds an MS from MIT and a BA in Architecture from Yale University, and spent much of that time working with artist/technologist Natalie Jeremijenko, building robotic dogs and stuff. To find out more, visit Unterbahn.com.
