Albrecht Karle

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.
