From major gatherings in the U.S., Europe, and Asia-Pacific to vibrant regional meetings worldwide, our symposia are the heartbeat of our open-science mission.
At the core of every event is the Collaborator Showcase—a bustling hub where researchers, clinicians, and developers gather to share groundbreaking work and learn directly from peers across the globe. It is the ultimate networking space, offering endless opportunities to spark conversations over posters, exchange ideas with global experts, and connect with future research partners.
Beyond the showcase, each event delivers a rich lineup of plenary talks, hands-on educational tutorials, and dedicated sessions to align with specialized working groups and regional chapters. Whether you are picking up new analytical skills or shaping policy with an international committee, there is a clear path to learn, lead, and contribute.
Because generating reliable, practice-changing evidence requires global collaboration at scale, these face-to-face gatherings are essential. But they are also unforgettable. From deep-dive workshops to unexpected community activities and spontaneous stage moments, every symposium blends serious science with a genuinely fun, welcoming atmosphere that sets new paths for future research.
