The concept of “science diplomacy” has become an increasingly fashionable way of discussing both the role of science and technology within global governance as well as how science itself constitutes a field of diplomacy. At a one and a half day workshop at Exeter College, from 12.-13.7., we are meeting to discuss the concept and how it can be used as a starting point for an innovative agenda. The goal is to identify mechanisms as well as cases representative of the science/diplomacy interaction. The event is part of the new science diplomacy project of the Department of Science, Technology, Engineering and Public Policy (STEaPP) of the University College London.
