The LSSTC Catalyst Fellowship funded by the John Templeton Foundation supports early career researchers in astrophysics and the social sciences. The Fellowship is focused on realizing the full potential of the Rubin Observatory’s Legacy Survey of Space and Time (LSST), both through new discoveries and creating exceptional opportunities for astrophysics and social science researchers, including those from traditionally under-represented groups and institutions. The astrophysics Fellowships support postdoctoral scientists to make discoveries during the run-up to LSST and during the early years of LSST.  The Fellowship are designed to train a diverse group of scientific leaders who are deeply and broadly familiar with LSST’s capabilities. The social science fellowships support early-career social scientists who will use a variety of methods to study the social aspects of this large scale and innovative scientific endeavor such as: how collaboration networks form; how interdisciplinary research can be fostered; how original contributions are developed; how gender and race influence scientific practice and mentoring; and how scientific practices are evolving with new, big, and open datasets.  The LSSTC Catalyst Fellowship is a foundational part of the LSST Interdisciplinary Network for Collaboration and Computing (LINCC).

During their Fellowships, astrophysics and social science Fellows will share knowledge and perspectives on the sociotechnical arrangements that produce astrophysics research and the broader social implications of astronomical science.  Diversity, equity, and inclusion will be prioritized in all aspects of the LSSTC Catalyst Fellowship Program. Fellows will develop critical connections with each other and with the Science Collaborations across the LSST community.

  • The Catalyst Fellowship will support at least two cohorts of Fellows. We are now soliciting applications for the first cohort of astrophysics Fellows, to be selected in early 2022. 
  • Fellowships will be held at US or international LSSTC member institutions, as well as other institutions that we refer to as expansion sites
  • Five astrophysics Fellows and 1-2 social science Fellows will be selected per cohort, for 3-4 year terms.
