Ellen Zweibel is the W. L. Kraushaar Professor of Astronomy and Physics at the University of Wisconsin–Madison , where she has been a faculty member since 2003. She holds a joint appointment in the Department of Astronomy and Physics . Zweibel earned her undergraduate degree in Mathematics from the University of Chicago and her Ph.D. in Astrophysical Sciences from Princeton University. Her research focuses on plasma astrophysics , particularly the evolution of astrophysical magnetic fields , cosmic ray feedback in galactic and intergalactic environments, and stellar differential rotation dynamics. Recent work examines cosmic ray interactions with the interstellar medium, magnetic instabilities in galaxy clusters, and turbulence-driven dynamo processes. Zweibel's publications highlight collaborations on missions like HelioSwarm and SOFIA/HAWC+ , including the discovery of a magnetized dust ring in the Galactic Center . She leads NSF-funded research on microscale plasma processes in high-beta environments and contributes to understanding magnetic reconnection across astrophysical contexts.
