Simons Investigator in Theoretical Physics (2015) Simons Fellow (2013) American Association for the Advancement of Science (2012) American Academy of Arts and Sciences (2010) Andrea Jo-Wei Liu (born 1962) is the Hepburn Professor of Physics at the University of Pennsylvania, where she holds a joint appointment in the Department of Chemistry.

She is a theoretical physicist studying condensed matter physics and biophysics.

[1] She is particularly known for her study of jamming, a phenomenon in which disordered materials become rigid with increasing density and stress.

Liu is recognized for distinguished contributions in theoretical physics, particularly for demonstrating that slow relaxation in soft materials can be viewed within a common framework called jamming.

According to Google Scholar, Liu's publications have received over 17,000 citations and her h-index is 63.
