For the first time in the history of the two conference series, the LIP-2018 and its sister-conference, the ELS-XVII, will be be held jointly in the same year. The LIP-2018 will include keynote lectures, oral sessions, and a poster session. The conference will begin with a full day of keynote lectures on Monday, which are held as joint plenary sessions for both LIP and ELS attendees. Likewise, the poster session, coffee breaks, and all social events are shared events.
