We welcome workshop proposals on topics within the scope of GC 2019, emerging research areas and applications, multi-discipline topics, and other miscellaneous topics that are well suited to the flexibility that a workshop format provides and that are expected to be of interest to a significant proportion of GC 2019 attendees. Workshops may consist of any subset of invited talks, paper presentations, discussion panels, and other activities that the workshop organizers would like to propose. The rooms provided for the workshops will have capacities ranging from 30 to 60. Papers submitted to the workshops for peer review should consist of new unpublished work and papers accepted to the workshops will be published in the workshops section of the GC proceedings.
