The Center for Astrophysics | Harvard & Smithsonian invites applications for postdoctoral research positions with Professor Daniel Eisenstein in the area of galaxy evolution, focusing on deep field observations with the James Webb Space Telescope.


The successful applicant will lead and participate in survey operations and science analysis of deep-field imaging and spectroscopic surveys with the James Webb Space Telescope, most immediately with the JADES survey.

Applicants with previous experience in the study of high-redshift galaxy evolution and/or cosmological reionization are encouraged to apply. Pertinent methodological experience includes data reduction and analysis of optical/IR imaging and spectroscopy, particularly with JWST, statistical methods for large data sets, and utilization of cosmological simulations.

Resources include access to large JWST-based data sets as well as observational capabilities with the MMT and Magellan telescopes. Professor Eisenstein is also a senior Investigator in the NSF AI Institute for Artificial Intelligence and Fundamental Interactions (IAIFI).

The position is for two years, renewable for a third year upon mutual agreement. The nominal starting date will be January 1, 2024, but an earlier or later start is negotiable.

Candidates must have a Ph.D. in astronomy, physics, or equivalent, by the date of appointment.

Applicants should submit a cover letter, CV, list of publications, and a statement explaining research interests and qualifications, and arrange for three letters of recommendation to be sent directly.

Review of applications will begin on November 27, 2023, and applications that are complete by that date will receive immediate and full consideration. Applications will close January 31, 2024, or earlier if the position is filled.

The CfA hosts a strong research program in astrophysics and provides a stimulating environment. Women and minorities are strongly encouraged to apply. AAE/EOE.
