John Bahcall Postdoctoral Researcher


The Wisconsin IceCube Particle Astrophysics Center (WIPAC) at the University of Wisconsin–Madison invites applications from outstanding postdoctoral candidates for the John Bahcall Fellowship to work in experimental or theoretical astroparticle physics.

This fellowship was created in honor of the late John Bahcall, an inspiring mentor to generations of young scientists, whose pioneering work on the physics of the sun was central to launching the field of neutrino astronomy. He was a founding member of the IceCube experiment, which has transformed a cubic kilometer of natural Antarctic ice into a particle detector. IceCube’s results are providing a new window on the universe to answer questions on topics as diverse as neutrino physics, supernovae, dark matter, gamma-ray bursts, active galaxies, and cosmic rays.

Position Description:

The successful candidate is expected to lead an independent research program as part of the WIPAC group in Madison. WIPAC has significant efforts in several areas of astrophysics and astroparticle physics, including neutrino astronomy, neutrino physics, gamma-ray astronomy, and cosmic-ray physics. Experimental affiliations include the IceCube neutrino detector, the Askaryan Radio Array (ARA), the High-Altitude Water Cherenkov (HAWC) experiment, and the Cherenkov Telescope Array (CTA). WIPAC is also involved in new initiatives in detector design and development in astroparticle physics.

The successful candidate will collaborate with faculty, scientists, research associates, and graduate and undergraduate students at WIPAC and have access to extensive research infrastructure at the center. The position comes with an independent research budget.


• Candidates must possess at least two years of post-Ph.D. experience in astrophysics, particle physics, or astroparticle physics.

• The ideal candidate will have experience in data analysis and/or detector development in neutrino, gamma-ray, cosmic-ray, or multimessenger astroparticle physics.


• Competitive salary.

• An independent research budget.

About WIPAC/IceCube:

The Wisconsin IceCube Particle Astrophysics Center (WIPAC) is a research center within the Office of the Vice Chancellor for Research and Graduate Education at the University of Wisconsin–Madison. WIPAC is responsible for the maintenance and operation of the IceCube Neutrino Observatory, a kilometer-scale neutrino detector at the South Pole, and has the broader mission to advance the field of particle astrophysics by supporting the design, construction, operation, and data analysis of a wide platform of experiments. The IceCube Collaboration is an international group of scientists who collectively participate in IceCube research to study high-energy neutrinos from cosmic sources.
