The Clay Postdoctoral Fellowship at the Smithsonian Astrophysical Observatory (SAO) fosters innovative astrophysics research through complete research independence and access to the Harvard and Smithsonian Center for Astrophysics (CfA). The CfA is a joint institution of SAO and Harvard College Observatory. The fellowship supports researchers demonstrating promise in theory, observation, instrumentation, engineering, and laboratory or experimental astrophysics.
Fellows can draw on ground- and space-based observing programs, specialized laboratories, technical and engineering teams, and expertise in artificial intelligence and data science. They are encouraged to collaborate across both observatories. The program also offers mentoring, opportunities to co-advise graduate and undergraduate students, participation in education and outreach, and support for workshops and scientific visitors. The 2027 position is in person in Cambridge, Massachusetts.
