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 2024, 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. Candidates with a primary focus on experimental quantum cosmology should apply to the Brinson Postdoctoral Fellowship.


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.


Qualifications and terms of appointment:

  • Applicant must have or should expect to receive a PhD in Physics, Astronomy, or related field by the time the fellowship begins
  • Applicants who are currently employed as postdocs are eligible
  • Appointment is for 3 years
  • Salary is $76,000 in the first year
  • Research fund of $10,000 per annum
