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. The bid winner for the 2020 IGAC Science Conference will be announced in late June 2018.
