Theoretical Physics Research Associate

We Are:
Fermilab is America’s premier laboratory for particle physics and accelerator research, funded by the U.S. Department of Energy.  We support discovery science experiments in Illinois and at locations around the world, including deep underground mines in South Dakota and Canada, mountaintops in Arizona and Chile, and the South Pole.

We are strategic risk takers, innovators, and collaborators. We are engineers, scientists, technicians, administrative professionals. We are 1,800 employees advancing knowledge for the benefit of humankind. Fermilab has been at the forefront of particle physics for more than 40 years. We build world-leading accelerators and detectors to conduct some of the most advanced particle physics experiments possible. We collect and analyze the data from those experiments with some of the most powerful computers in the world. We conduct this research on a 6,800-acre prairie, 35 miles outside Chicago, a treasure that has been designated a National Environmental Research Park.

Open Date: September 22, 2022
Close Date: November 11, 2022

The Fermilab Theory Division/Particle Theory Department invites applications for postdoctoral research appointments starting in the fall of 2023. Postdoctoral research associates in the Fermilab Theory Division are appointed for three years.  

They are expected to perform self-directed theoretical physics research on topics of their own choosing, and are encouraged to work with members of the senior scientific staff and other postdocs within the Division. The Fermilab Particle Theory research program includes neutrino physics, perturbative QCD, lattice QCD, Higgs & flavor physics, collider phenomenology and physics beyond the standard model. Collaboration with members of the other two departments in the Theory Division (Astrophysics Theory and Quantum Theory) is encouraged and supported.
The senior staff of the Particle Theory Department consists of John Campbell, Marcela Carena, Bogdan Dobrescu, Patrick Fox, Walter Giele, Roni Harnik, Stefan Hoeche, Andreas Kronfeld, Pedro Machado, Stephen Parke, Noemi Rocco, Ruth Van de Water and Michael Wagman. The emeriti are William Bardeen, Estia Eichten, Christopher Hill, Boris Kayser, Paul Mackenzie and Chris Quigg. Our colleagues in the Astro Theory Department are Joshua Frieman, Nick Gnedin, Craig Hogan, Dan Hooper, Gordan Krnjaic and Albert Stebbins, and in the Quantum Theory Department Asher Berlin and Henry Lamm. 

Further details can be found on our website:

  • Candidates should have obtained a Ph.D. in theoretical particle physics or astrophysics, or a closely related field, or expect to earn a Ph.D. in the same fields, by September 1, 2023.
