The creator of GrassrootsMapping.org and co-founder and Research Director for Public Lab, Jeffrey Warren designs mapping and community science tools and professionally flies balloons and kites. He leads the coding community at Public Lab, and has developed the vector-mapping framework Cartagen and grassroots mapping tool MapKnitter, as well as open spectral database and toolkit Spectral Workbench.

He is on the board of of the Open Source Hardware Association and served from 2015-17 as Vice President, is on the board (since 2014) of alternative education program Parts and Crafts in Somerville MA, and an advocate of open source software, hardware, and data.
