EXP Fellowships in Experimental Physics and Astrophysics

About this position

• The Caltech Division of Physics, Mathematics and Astronomy offers a
• number of named Experimental Physics and Astrophysics Postdoctoral
• Prize Fellowships (EXP Fellowships). EXP Fellowships are for a
• three-year duration and to begin in the Fall 2027, or a mutually
• agreeable date.

• The EXP program has been established to offer scientists, typically
• within a few years after receipt of their PhD, the opportunity to
• pursue innovative experimental research, including but not limited to
• Astrophysics, Atomic Molecular and Optical Physics, Biophysics,
• Condensed Matter Physics, Soft Condensed Matter Physics, Gravitational
• Physics (via the dedicated Braginsky/Whitcomb Fellowship), High Energy
• Physics, Low-Energy Particle Physics, Nuclear Physics, Quantum
• Information, or Cosmology.

• It is expected that this research will require the support and
• facilities of one of the established experimental groups at Caltech
• (accessible from this list). Prospective applicants are encouraged to
• contact faculty members to gauge mutual interest.

• In the case of astrophysics, only candidates with a focus on
• instrumentation and/or experimental laboratory work will be considered
• for EXP fellowships.

• Electronic copies of the curriculum vitae, publications list (refereed
• papers on top), and statement of research interests are required. The
• research statement should be no more than 5 pages, excluding
• references. The applicant is requested to ensure that at least three
• letters of recommendation are submitted on their behalf.
