I work with open data research, policy and practice at the Web Foundation, driving Open Data Barometer research and other open data projects. I also consult for the Global Open Data for Agriculture and Nutrition (GODAN) Secretariat on the development of the international Open Data Charter's Agriculture Sector Package. My previous work has included global advocacy, research evidence and mapping, policy, and strategic partnerships in open data for agriculture and nutrition, participatory mapping in Africa, Caribbean and the Pacific, development of pioneering the Open Contracting Data Standard, crowdmapping and community development in Canada, geovisualizing trauma injuries in South Africa, and representing informal communities with free and open source software tools in India.
