In October of 2026, an international community of investigators including undergraduates, technicians, graduate students, postdocs, and faculty will convene for the 29th Developmental Biology of the Sea Urchin and other Marine Invertebrates (DBSUMI) conference at the Marine Biological Laboratory. We will enjoy 3 days of plenary and concurrent sessions from invited speakers and selected abstracts, as well as two evening poster sessions and two Pre-Meeting Workshops. Brand new to the DBSUMI Meetings, we introduce a "Lightning Talk" competition for students and trainees to promote poster attendance. We will also have a panel on teaching EvoDevo and broadening participation in science in groups historically not included in scientific education or research. We invite all participants to consider contributions to a future Conference Publication Collection, generously sponsored by Discover Developmental Biology.
