The IONS-Project is open to all young scientists who are members of an e.g. OSA or SPIE Student Chapter. If you want to attend an IONS Conference, check out the European, North American, Asian and Australasian branches, and contact the local organisers.
Attendance to our conferences, including the conference programme and meals, is generally free, thanks to generous support by sponsors 1. However, we do not provide travel reemburses; you will have to seek funding for accomodation and travel yourself.
(1) Some conferences might ask for a small registration fee
