Agenda for Workshop Week 2018!


Location: Ogden Centre West, OCW017 (ground floor)

(post/zip code: DH1 3LE)

Talks should be nominally 20-25 minutes long. Since this is a workshop and discussion is encouraged, we will try to allow some flexibility in the time slots, and the audience will be invited to ask questions within talks as well as at the end. Each section of 2-3 talks will end with a dedicated discussion session (shared with coffee or lunch). At the end of each day, we have reserved a longer period for discussion.

Instructions to presenters: This is a workshop, not a conference. Therefore please try to introduce some points for discussion. Be open and honest about issues and problems you've been having, so that these can become discussion points.
