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. IGAC is now soliciting bids for a host location and local organizing committee for the 16th IGAC Science Conference in 2020. Bids are due 13 April 2018 to the IGAC Executive Officer Megan L. Melamed (email@example.com). Bid requirements are available here for download.
