Description

2027 CfA Prize Postdoctoral Fellowship

August 2026

The Center for Astrophysics | Harvard & Smithsonian (CfA) is a joint institution of the Smithsonian Astrophysical Observatory (SAO) and the Harvard College Observatory (HCO).  The CfA is a diverse astrophysical institution where more than 800 staff and students are engaged in a broad program of research and education in astronomy, astrophysics, and earth, planetary and space sciences. The CfA is at the international forefront of the scientific exploration of the universe. Our research covers theoretical astrophysics, observational ground and space-based astronomy, engineering and technology development, and education. The research objectives of the CfA are carried out primarily with support from the federal government, the Smithsonian Institution, Harvard, and philanthropy. At the CfA, the next generation of scientific leaders are being trained and mentored through a broad range of postdoctoral positions and fellowships as well as graduate and undergraduate student programs.

For more than 50 years, the CfA has been a recognized global leader in astronomy research, instrumentation and outreach. Drawing on our strengths that span theory, laboratory astrophysics, observations, and in-house engineering, the CfA’s 2026-2036 Decadal Plan is an integrated strategy that will sustain and build on that leadership and maximize the scientific and societal impact of our work in the decade ahead. The CfA Decadal Plan is available here:

The mission of the CfA Postdoctoral Fellowship program at SAO is to foster innovative astrophysics research by providing independent researchers full access to the facilities, research staff, and resources of the CfA. A list of past CfA Postdoctoral Fellows is available on the CfA website.

Applications are now open for the 2027 CfA Postdoctoral Fellowship.

Successful candidates will be outstanding researchers with demonstrated promise in theory, observation, instrumentation, engineering, and/or laboratory or experimental astrophysics. This opportunity is open to all qualified applicants who are English-speaking citizens from any nation.

Eligible candidates must be within 24 months or less of equivalent full-time post-PhD research experience at the time of the fellowship start date of September 1, 2027. If the PhD defense date (or acceptance of PhD thesis) and the official PhD award date differ, please refer to the PhD defense date (or acceptance of PhD thesis). Time taken for family leave, career duties, illness, or other career gaps does not count towards the 24 months of post-PhD full-time equivalent research (FTER) and should be noted in the CV.

About the Center for Astrophysics | Harvard & Smithsonian (CfA)

The CfA is known for its leadership in theoretical, observational and laboratory astrophysics, and for its observational programs across the electromagnetic spectrum. The CfA also includes highly successful instrument development teams and facility operations expertise. Fellows are encouraged to use the combined resources and facilities of the CfA’s two collaborating observatories – the Smithsonian Astrophysical Observatory and the Harvard College Observatory.

Through the CfA’s operational agreements with its partners, Fellows can propose for CfA-allocated observing time on the MMT in Arizona, the Magellan Telescopes in Chile, and the Submillimeter Array in Hawai’i. Fellows participate in ground- and space-based observing programs including but not limited to the Chandra X-ray Observatory, the Event Horizon Telescope, the TEMPO satellite instrument for pollution monitoring, the Parker Solar Probe, the James Webb Space Telescope, the Hubble Space Telescope, the Transiting Exoplanet Survey Satellite, Kepler K2, the Solar Dynamics Observatory, and the Atacama Large Millimeter Array. The CfA is a founding member of the Giant Magellan Telescope project and operates a world-class engineering program that develops leading ground and space telescope instrumentation. The CfA also has established programs in artificial intelligence and data science, and a number of specialized laboratories and initiatives that focus on a particular research area (for example in black holes, theoretical astrophysics, and the origins of life), where interdisciplinary and collaborative research is the central organizing principle. 

Currently led by Director Lisa Kewley, the CfA provides a dynamic range of weekly luncheons, colloquia, journal clubs, daily coffees, and divisional events. The CfA also supports many other formal and informal opportunities for the exchange of ideas and professional development in a diverse scientific community.  Fellows have access to institution-wide funding for organizing workshops, conferences, and visitor programs.

The CfA is located in Cambridge, Massachusetts, a vibrant community in the Boston metropolitan area, known for excellent universities, colleges, and public schools, world-renowned medical facilities and teaching hospitals, a dynamic technology hub, a lively art scene, passionate sports fans, and diverse cultures. Cambridge is also a two- to three-hour drive to downhill and cross-country skiing, cycling, and hiking in the White, Green and Berkshire mountains, and many Atlantic Ocean beaches and craggy coastlines are nearby.
