Albrecht Karle

    Albrecht Karle is the IceCube associate director for science and instrumentation, the principal investigator for ARA, and a professor of physics at the University of Wisconsin–Madison. His research is focused on high-energy neutrino astronomy and astrophysics. With IceCube, he focuses on research with neutrinos of all flavors at energies above 30 TeV. He is also exploring new ways to detect ultra-high-energy neutrinos using radio detectors. Karle currently mentors several graduate students and postdocs.  Karle’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.

    Visitors

    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.

    Fellows

    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.
