The California Institute of Technology (Caltech) solicits applications for the Prize Fellowship program of the Walter Burke Institute for Theoretical Physics and the newly founded Leinweber Forum for Theoretical Physics. Fellowships are to begin in the Fall 2026, offering an opportunity for outstanding recent and new Ph.D. recipients to perform research at Caltech for three to four years. Application deadline November 15th 2025.
They are selected by a faculty committee representing all areas of theoretical physics and astrophysics at Caltech and are provided with:
flexibility, support, and freedom in choosing research directions within theoretical physics and astrophysics (including but not limited to theoretical astrophysics/cosmology, condensed matter theory, general relativity, particle/string theory, mathematical physics, and quantum information),
an inclusive environment with faculty mentorship and activities organized by the Burke Institute and Leinweber Forum to promote scientific exchanges and professional growth.
The Burke and Leinweber Fellowship program significantly expands and strengthens Caltech’s long-standing program of Prize Fellowships in Theoretical Physics and Astrophysics. The Prize Fellowship program has been successful with over 95 percent of the more than 120 former fellows holding distinguished academic positions, as shown at http://burkeinstitute.caltech.edu/people/postdoctoral-fellows.
Applicants should submit curriculum vitae, a statement of research interests (no more than 5 pages, excluding references), and a list of publications (refereed papers on top). Applicants should also ensure that at least three letters of reference are submitted on their behalf.
Applicants interested in being considered for a joint appointment in theoretical astrophysics with Carnegie Observatories must also apply here.
