John Ketterson

John Ketterson is a Professor at Northwestern University's Department of Physics and Astronomy, jointly affiliated with Electrical Engineering. He earned his PhD from the University of Chicago in 1962.

• PhD, University of Chicago (1962)

His research spans magnetic and superconducting properties of bulk and nanostructured materials, with a focus on quantum collective behavior, and optical phenomena involving excitons and plasmons. He directs the Magnetic and Physical Properties Measurement Facility, a critical resource for interdisciplinary measurements of magnetization, thermal transport, and microwave absorption.

The 15 most recent publications highlight his work on superconducting vortex dynamics, spin-wave instabilities, Josephson junctions, and hybrid perovskite materials. These reflect trends in quantum materials, nanomagnetism, and nonlinear optical responses.

• Fellow, American Physical Society
• Fellow, American Association for the Advancement of Science

His laboratory supports advanced research in magnetic and superconducting systems, with emphasis on experimental characterization of quantum and nanoscale phenomena.
