GPI has been built by a consortium of U.S. and Canadian institutions, funded by the Gemini Observatory, which is an international partnership comprising the U.S.A., U.K., Canada, Australia, Argentina, Brazil & Chile. The GPIES campaign is partially funded by NSF, NASA, the University of California and the Laboratory Directed Research and Development funding at the Lawrence LIvermore National Laboratory.
