The International Symposium on Physics of Unstable Nuclei 2017 (ISPUN17) will be held in Halong Bay (Vietnam) from September 25th to September 30th, 2017, to mark 15 years of the ISPUN series which started in 2002 with ISPUN02 held in the same location. ISPUN17 is organized by the Institute for Nuclear Science and Technology (INST) and Institute of Physics (IOP) in Hanoi, and French counterparts in the collaboration in nuclear physics research between IPN Orsay (CNRS), IRFU (CEA) of France and INST, IOP of Vietnam. It is officially supported and endorsed by Ministry of Science & Technology of Vietnam (MOST), Vietnam Academy of Science and Technology (VAST), French CNRS and CEA, Helmholtz International Center (HIC) for FAIR, Asia Pacific Center for Theoretical Physics (APCTP), and Asian Nuclear Physics Association (ANPhA). Like previous ISPUN meetings, ISPUN17 is aimed at bringing together not only leading nuclear physics researchers but also young physicists and post-graduate students currently involved in the forefront research in nuclear physics for the exchange of new ideas, information, and presentation of the latest research results.
