Job Description

Postdoctoral positions – Caltech/IPAC, Roman Galaxy Redshift Survey Project Infrastructure Team

The Nancy Grace Roman Space Telescope, NASA’s next flagship mission in astrophysics, will be launch-ready in October 2026. The Roman Project Infrastructure Teams (PITs) have sustained funding to partner with the Science Centers in developing the infrastructure needed by the community to pursue Roman’s ambitious science goals. Caltech/IPAC is home to the PI (Yun Wang) and several Co-Is and Collaborators of the Roman Galaxy Redshift Survey (GRS) PIT. We seek two postdoctoral scholars to join the Roman GRS PIT team as Roman Junior Scientists, with work focused on deliverables to the NASA Roman Project, in the areas of (1) grism data simulation and analysis and (2) cosmological analysis of galaxy clustering data.

Experience with the analysis of slitless spectroscopic data or galaxy redshift survey data is highly desirable. The successful candidates will also be encouraged to pursue their own independent research programs, and will have IPAC institutional access to the Palomar 200-inch telescope. They will also have the opportunity to work with Euclid data under the guidance of Dr. Wang, in view of the strong synergy between Roman and Euclid.

The applicant must have a Ph.D. in astronomy, astrophysics, or physics prior to the start date of the position. The application must include: cover letter, CV, publications list, and statement of research experience and interests (1-3 pages). Three reference letters should be emailed directly by the references to the same email addresses as the applications. Application should be sent to [email protected] by December 31, 2023. There is flexibility in the start date, which ranges from spring to fall 2024.

The Roman GRS PIT team members will closely collaborate and frequently interact with each other. Roman GRS Junior Scientists will be actively mentored, and given opportunities to represent the team at major conferences. They will retain team membership upon completion of their terms, provided they continue being active on the team. Each Roman GRS Junior Scientist position has a 3-year term, renewed annually upon satisfactory performance, subject to the availability of funding. For more information, see
