Global Solutions Fellows

The Global Solutions Initiative’s Fellows program encourages recognized researchers, policy advisors and thought-leaders to engage with scholars, implementers and civil society to bring research-based insights to the GSI network, the Group of 20 (G20) and Think20 (T20) processes, and the wider public.

Global Solutions Fellow positions are open to outstanding researchers, thought-leaders and policy advisors who have made an ongoing commitment to supporting the G20 policy process. Our fellows produce innovative, implementable recommendations for tackling global problems, they have a strong voice in the public debate on global issues and are well-connected to policymakers concerned with global problem-solving.

Global Solutions Fellows participate in activities of the Global Solutions Initiative and contribute to its research and interaction with policymakers. The Global Solutions Initiative’s staff offers its fellows privileged support in the fulfillment of their roles.

Appointed for a three-year period, it is standard practice to invite Global Solutions Fellows to speak at the Global Solutions Summit, the Initiative’s annual conference in Berlin. Global Solutions Fellows play a significant role in the T20/G20 policy process leading up to the Global Solutions Summit by helping shape the event’s agenda and various workshops around G20 priorities. Global Solutions Fellows also help identify future contributors in the T20/G20 process, future speakers for the annual summit and candidates for the Council for Global Problem-Solving.

Progress in the Global Solutions Fellows’ global problem-solving efforts is assessed annually and future collaboration with the Global Solutions Initiative is developed on this basis.
