Users Committee

The 12-person Rubin Users Committee will stand throughout Rubin Observatory’s commissioning and operations phases. The committee is charged with soliciting feedback from the science community and recommending science-driven improvements to the LSST data products and the Rubin Science Platform tools and services. This committee reports every six months to the Rubin Lead Community Scientist and to the Rubin Observatory Director. The full charge to the Users Committee can be found at

Meetings of the Users Committee will be (at least in part) open to any members of the Rubin community. A meeting calendar is posted below, and connection information will be provided here and in the Rubin Community Forum.

The current members of the Rubin Users Committee are listed below. The chair of the Users Committee and primary contact member is Matthew Holman.

The Users Committee is open to suggestions and feedback from the Rubin community. Users Committee members can be contacted individually via direct message in the Rubin Community Forum, or all together by sending a direct message to the Rubin Community Forum group @Users-Committee or an email to

Financial support for Rubin Observatory comes from the National Science Foundation (NSF) through Cooperative Agreement No. 1258333, the Department of Energy (DOE) Office of Science under Contract No. DE-AC02-76SF00515, and private funding raised by the LSST Corporation. The NSF-funded Rubin Observatory Project Office for construction was established as an operating center under management of the Association of Universities for Research in Astronomy (AURA).  The DOE-funded effort to build the Rubin Observatory LSST Camera (LSSTCam) is managed by the SLAC National Accelerator Laboratory (SLAC).
The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 to promote the progress of science. NSF supports basic research and people to create knowledge that transforms the future.
NSF and DOE will continue to support Rubin Observatory in its Operations phase. They will also provide support for scientific research with LSST data.
