Three faculty elected fellows of American Physical Society

Tue, 09/24/2019

Three professors – representing the departments of physics, materials science and engineering, and electrical and computer engineering – have been elected fellows of the American Physical Society (APS).

The fellowship program recognizes physicists who have made exceptional contributions in physics research, important applications of physics, leadership in or service to physics, or significant contributions to physics education.

Matthias Liepe, professor of physics in the College of Arts and Sciences, was elected for multiple contributions to the fundamental science and engineering of radiofrequency superconducting materials, accelerating cavities, cryomodules, and instrumentation and controls. He was also honored for excellence in graduate and undergraduate physics education. Liepe studies the science, technology and applications of bulk and thin-film superconductors in high electromagnetic fields at ultra-high frequencies.

James Sethna, professor of physics in the College of Arts and Sciences, was cited for seminal and wide-ranging contributions to information geometry, “sloppy models,” crackling noise, fracture and emergent self-similarity. His work explores how multiparameter, or “sloppy,” models behave collectively; his team is using statistical mechanics to understand plasticity and fracture in disordered materials.
