Postdoctal Fellow, N3AS

Position Description N3AS Physics Frontier Center Fellows The NSF Physics Frontier Center Network for Neutrinos, Nuclear Astrophysics, and Symmetries (N3AS) intends to make two postdoctoral Fellow appointments for positions starting in fall 2027. N3AS is a multi‑institutional collaboration linking thirteen partners: UC Berkeley, UC San Diego, U. Kentucky, Los Alamos National Laboratory, U. Minnesota, U. of New Hampshire, North Carolina State U., Northwestern U., Notre Dame U., Ohio U., Pennsylvania State U., U. Washington, and U. Wisconsin. N3AS research focuses on theoretical issues in multi‑messenger astrophysics. Topics include dark matter, dense matter, neutrino physics, nucleosynthesis, neutron stars and their mergers, supernovae, and associated gravitational wave physics. N3AS interests also include fundamental symmetries and weak interactions. N3AS provides a unique multi‑disciplinary environment for postdoctoral Fellows to address fundamental questions in astrophysics, cosmology, nuclear physics, and particle physics. All N3AS appointments are made through UC Berkeley. N3AS postdocs spend their initial two years at one of the N3AS host institutions. This year the available hosts are U. Kentucky and Los Alamos National Laboratory. N3AS Fellows then continue for a third year, moving to new Network institution of their choice (all sites are available). Fellow salaries depend on experience, beginning at $78K for new PhDs. N3AS provides a generous allowance to enable travel to other N3AS institutions and to support collaborative research, as well as a relocation allowance. More details on N3AS can be found at Candidates should have a recent Ph.D. (on or after August 2024) in theoretical physics or astrophysics and the ability to work productively within a diverse and collaborative research environment, producing and publishing original research, and defending that research effectively in seminars and scientific meetings. Requested application materials: a CV, a publication list, a statement of research interest, and three letters of reference. The N3AS Fellows selection committee includes all N3AS faculty. Interested candidates are requested to submit their applications before December 7, 2026, to ensure full consideration.
