Justin Vandenbroucke

Justin Vandenbroucke is an assistant professor in the Department of Physics at the University of Wisconsin–Madison, with a joint appointment in the Astronomy Department. His work at WIPAC includes research in gamma-ray and neutrino astronomy and cosmic rays. Vandenbroucke is the Principal Investigator for the Distributed Electronic Cosmic-Ray Observatory, DECO, a citizen science project that allows users around the world to detect cosmic rays and other energetic particles with their cell phones and tablets.  In addition to his work with DECO, Vandenbroucke is a member of the IceCube, Cherenkov Telescope Array, and Fermi collaborations. Currently he is teaching Advanced Laboratory and Graduate Laboratory and is accepting inquiries for graduate and undergraduate research positions. Vandenbroucke’s complete CV is available to download

Faculty Profiles

WIPAC faculty and students are involved in IceCube, the Askaryan Radio Array (ARA), the High-Altitude Water Cherenkov (HAWC) experiment, Cherenkov Telescope Array (CTA), Big Data, and DM-Ice.


In keeping with our vision, we encourage and support visits from researchers who have interests, or who wish to develop interests, in several of our research areas.


The postdoctoral fellowship program was created to honor the late John Bahcall, a prominent physicist and a founding member of the IceCube experiment.  In 2015 the Balzan Fellowship was created after Francis Halzen was awarded the Balzan Prize.
