Postdoctoral Research Associate in High Energy Phenomenology University of Toronto in Canada

The Waterloo Centre for Astrophysics at the University of Waterloo is offering postdoctoral fellowships in theoretical astroparticle physics and cosmology through the McDonald Institute Theory Fellowship and McDonald Institute CITA Theory Fellowship streams. The fellowship is designed for researchers interested in cosmological and astrophysical probes of neutrino mass and dark matter, with connections to major surveys and experiments such as DESI, Euclid, Roman, SNO+, DarkSide-20k, SuperCDMS and...

Queen’s University and the Arthur B. McDonald Canadian Astroparticle Physics Research Institute are offering postdoctoral fellowship opportunities in the High Energy and Astroparticle Theory group. The fellowship sits at the intersection of astroparticle theory, particle phenomenology, cosmology, the astrophysics of dark matter, and high-energy theory, with a start date in the 2027-2028 academic year. Successful fellows will join a research environment that includes faculty Joseph Bramante and A...

The Department of Physics at Arizona State University invites applications for a full-time Postdoctoral Research Scholar in the Targeted Simons Research Group on Cosmic Magnetism . The position is based on the Tempe campus and is part of a collaborative, multi-institutional team focused on all aspects of cosmic magnetic fields. The successful candidate will join a research environment that combines theoretical high-energy physics, cosmology, and astrophysics. The project centers on the generatio...

The Theoretical Particle Physics and Cosmology Group in the Physics Department at King's College London is recruiting for two postdoctoral positions starting in October 2027. The appointments sit within a research environment that brings together work on beyond-the-Standard-Model particle physics, collider phenomenology, and LHC physics, alongside projects at the interface of particle physics, astrophysics, and cosmology. The advertised themes also include gravitational-wave physics, with an emp...

Carleton University in Canada is advertising one or two postdoctoral fellow positions in the Theoretical Particle Physics group, with a planned start in Fall 2027. The main research area is theoretical astroparticle physics, broadly defined, within a group that also works on beyond-the-Standard Model physics. The department has a strong particle physics environment and connections to experimental efforts including ATLAS, dark matter, and neutrino experiments. The appointment is for 2+1 years, wi...
