Every summer from 1 June to 31 August, the International Institute for Applied Systems Analysis (IIASA) near Vienna, Austria, hosts up to 50 doctoral students from around the world in its Young Scientists Summer Program (YSSP). Each YSSP participant works on a topic related to his or her PhD thesis and IIASA’s research agenda, the goal being to write a publishable paper. All YSSP participants are personally mentored by IIASA senior scientists.
