THE Asean Science and Technology (S&T) Fellowship was held last June 23-30, 2019, in Nusa Dua, Bali, Indonesia. This was organized by the Association of Southeast Asian Nations (Asean), the Asean Foundation, the United States Agency for International Development (USAid) and the US Mission to Asean. This program aims to foster a culture of science-based policy-making throughout the region by providing opportunities for early and mid-career scientists from Asean member states to contribute their knowledge and analytical skills to their national governments.
