Program Description:    

Flatiron Research Fellow, CCA

Applications are invited for postdoctoral research positions as Flatiron Research Fellows (FRF) at the Center for Computational Astrophysics (CCA). The CCA offers FRFs the opportunity for independent research in areas that have strong synergy with the CCA or other centers at the Flatiron Institute.

The mission of the Flatiron Institute is to advance scientific knowledge through computational methods, including data analysis, theory, modeling, and simulation. It currently houses five centers, focused on computational astrophysics (CCA), biology (CCB), mathematics (CCM), neuroscience (CCN) and quantum physics (CCQ), as well as a scientific computing core (SCC) that maintains state-of-the-art computing facilities for use by Flatiron scientists. The CCA's mission is to create, develop, and disseminate computational methods, tools, and frameworks that allow scientists to build or analyze big astronomical datasets, and to use computational and statistical techniques to understand complex, multi-scale physics in astrophysical systems ranging in scales from planets to the Universe.

Please see for a full description of CCA research areas and scientific staff.

Flatiron Research Fellows are expected to carry out an active research program that can be independently directed and/or involve substantial collaboration with other members of the CCA or Flatiron Institute. In addition to their own research, Fellows help build the rich scientific community at the CCA and Flatiron Institute by: participating in seminars, colloquia, and group meetings; developing their software, mathematical, and computational expertise through internal educational opportunities; and sharing their knowledge through scientific publications, presentations, and/or software releases. Flatiron Research Fellows may also have the opportunity to organize workshops and to mentor graduate and undergraduate students through the CCA Pre-Doctoral Program, the CUNY Astrophysics Masters Program, the Simons-NSBP Scholars Summer Program, and the AstroCom NYC Program. FRFs are welcome to take advantage of CCA partnerships with the Simons Observatory, the Terra Hunting Experiment, Sloan Digital Sky Survey V, Gaia, HIRAX, and the NASA SPHEREx mission. In addition, individual CCA research scientists have significant roles in a variety of collaborations and projects, including Learning the Universe, SIMBIG, Vera Rubin, Euclid, Roman, CAMELS, MESA, AstroPy, NANOGrav, and would welcome FRF collaborators. Many CCA scientists have joint appointments with other neighboring institutions as well.

The CCA welcomes any applicant who feels that their research program would thrive at the CCA. We have also identified a number of strategic areas where we would particularly welcome applicants' participation, listed on this webpage under the "Strategic Areas" tab.

FRF positions are generally two-year appointments that can be renewed for a third year, contingent on performance. FRFs receive a research budget and have access to the Flatiron Institute's powerful scientific computing resources. FRFs may be eligible for subsidized housing within walking distance of the CCA. These positions will be based in our New York City offices, with anticipated start dates between late August and early October 2024.

In addition, The Center for Computational Astrophysics at the Flatiron Institute and the Astronomy Department at Columbia University invite applications for a joint postdoctoral position. The chosen applicant of this position will conduct independent research as well as contribute to the goals of the Learning the Universe collaboration ( If you are interested, please review the full job ad, and indicate your interest when prompted in the Simons Foundation's application questionnaire.
