technology and innovation activities and policies in the era of uncertainty. The global political environment is experiencing dramatic changes in recent years. In the US, swift policy changes have been initiated under the new Trump administration, such as the restriction of travel and employment requirement for foreigners, and the reduction and even termination of research funding in some fields is to be expected. In Europe, the aftermath of Brexit is still unsettled but will have repercussion for European science. All of these developments will certainly affect the scientific community and research activities in the region, and the change will soon spread to the rest of the world. In this context, the workshop intends to explore how uncertainty affects scientific talent, research collaboration and government responses.
