Dear colleagues, the LSST Corporation announces its Catalyst Fellowship Funded by the John Templeton Foundation for postdocs in the social sciences (broadly construed). The Catalyst Fellowship in social science supports early-career researchers to study social aspects of the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) for up to three years. Prospective applicants may be interested in, for example, collaboration networks, the social organization of large-scale collaborations, broader implications of astronomical science, and methods for studying socio-technical systems. The social science postdocs will be part of a cohort with astrophysics postdocs and will be supported by a broad network of renowned mentors to realize the full potential of Rubin Observatory's LSST. Applicants can propose to work at any LSSTC member institution (https://www.lsstcorporation.org/node/3<https://urldefense.com/v3/__https:/www.lsstcorporation.org/node/3__;!!DZ3fjg!7LbGp48wbgFdG5QFSSyC7XKjGGx0OB5q-GHxd4EktgKuu227e-MtqJe7Z8d-FfIRJIebO0xRtKBkmIT1UVYqeRhPAFbvOz5a6BmW-T1K$>) with a faculty supervisor of their choice.
