IGAC's biennial Open Science Conferences are the primary mechanism for dissemination of scientific information across our community. The conference is held jointly with iCACGP quadrennially. A special effort is made to engage early career scientists and scientists from emerging countries. Since 2004 the IGAC Early Career Program has been an integral part of the conference.
