DAE 2024 will bring together researchers and practitioners to discuss ideas and techniques for designing and analyzing effective experiments. As with earlier meetings, this twelfth convening of the successful DAE series emphasizes interaction and encourages participation of young researchers, while focusing on rapidly evolving developments in both theory and practice. Each of the topic sessions will feature at least one early-career speaker. There will be poster sessions, roundtable discussions, a student award competition, and mentoring opportunities. Financial support will be provided (subject to funding) for student attendees, and to others as available.
