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. 

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 two-year period, it is standard practice to invite Global Solutions Fellows to partake in the Global Solutions Summit, the Initiative’s annual conference in Berlin. Fellows consult in aspects of its program and assist in finding qualified speakers. Furthermore, fellows are actively involved in the various programs of the GSI by participating and speaking at events such as workshop sessions, producing content that is aligned with the work of the GSI, and consulting on issues surrounding the G20 and G7.  

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.
