Ever wonder why coffee grounds get stuck in the filter or why it’s so difficult to clear a traffic jam?

Andrea J. Liu, professor of physics at the University of Pennsylvania, will be on the West Virginia University campus Dec. 6-7 to answer just those questions and otherjammingconundrums of modern life.

Liu will lecture onJamming: Why Things Get Stuckat 8 p.m. Monday, Dec. 6, in the Mountainlair Rhododendron Room. The lecture is open to the public.

She will also present a Department of Physics colloquium onThe Physics of How Cells Crawl and Listeria Spreadsat 4 p.m. Tuesday, Dec. 7, in 260 Hodges Hall. She will also meet with students and the local chapter of the Association for Women in Science during her visit.

Liu’s research in theoretical condensed matter physics and theoretical physical chemistry focuses on the statistical mechanics of jamming and biophysical systems. She co-edits Jamming and Rheology and is on the editorial boards of the Journal of Statistical Physics and Soft Materials .

She also serves on the executive committee of the Division of Condensed Matter Physics of the American Physical Society and the advisory board of the Kavli Institute of Theoretical Physics.

Her visit is sponsored by Phi Beta Kappa, the WVU Department of Physics and the Eberly College of Arts and Sciences.
