• Graham Thiele is a freelance consultant. From 2012 through 2021 he was Director of the CGIAR Research Program on Roots, Tubers and Bananas (RTB) which brings together multiple partners to improve food security and reduce rural poverty through research for development. He provides intellectual leadership to develop a shared vision, build a strong partnership among participating centers, partners and other stakeholders and manage for outcomes. Led by the International Potato Center, it includes Bioversity International, CIAT, CIRAD and IITA as managing partners. • He previously led social and health science research at the International Potato Center encouraging a shift to proactive impact enhancement rather than just documenting adoption and impact. • Prior to that he jointly coordinated the Papa Andina Partnership Program. Papa Andina and its partners in the Andes introduced novel approaches to value chain driven innovation with significant impacts on small farmer welfare through improved market linkage and adoption of "new" technology, including both improved and previously undervalued native potatoes.
