Postdoctoral Research Associate, Steward Observatory (Multiple Positions) Posting Number: req27287 Department: Steward Observatory Department Website Link: Location: Tucson Campus Address: Tucson, AZ USA Position Highlights The Arizona Cosmology Lab, a research unit of the University of Arizona (UA) Department of Astronomy and Steward Observatory (SO), invites applications for the Arizona Cosmology Lab Fellowship (multiple hires expected). Fellows conduct independent research in cosmological data analysis broadly, spanning research in theoretical and numerical modeling of cosmological, astrophysical, and gravitational-wave observables; development of statistical-inference and machine-learning methods; direct analysis of current and future surveys or experiments. As members of the Arizona Cosmology Lab, fellows will be provided with priority access to UA and national supercomputing resources, close mentorship by experienced faculty, and opportunities to co-advise graduate students and mentor undergraduates. UA offers a world-class research environment in astrophysics with strong interdisciplinary programs across the Departments of Astronomy, Physics, Planetary Sciences, the UA Data Science Institute, UA Space Institute, and NSF's NOIRLab. Start dates range from August - October 2027. Outstanding U of A benefits include health, dental, vision, and life insurance; paid vacation, sick leave, and holidays; U of A/ASU/NAU tuition reduction for the employee and qualified family members; access to U of A recreation and cultural activities; and more!
