Amalie L. Frischknecht is a Principle Member of Technical Staff at Sandia National Laboratories, and a staff scientist at the Center for Integrated Nanotechnologies (CINT), a DOE Nanoscale Science Research Center and user facility at Sandia and Los Alamos National Labs. She received her PhD in Physics from the University of California, Santa Barbara, in 1998, and went on to postdocs at ExxonMobil Research and Engineering Company (1998-2000) and at Sandia National Laboratories (2000-2003), before becoming a member of technical staff at Sandia in 2003. Amalie is a Fellow of the American Physical Society (APS), and is currently serving as Chair of the APS Division of Polymer Physics. She previously chaired the Gordon Research Conference on Polymer Physics (2018). Her research interests are in the statistical mechanics and molecular simulation of complex fluids, including polymer nanocomposites, ion-containing polymers, and charged soft matter systems. Her recent work has included a focus on understanding ion transport in polymer membranes for energy applications.

Research Interests

Morphology and ion transport properties of polymeric membranes

Properties of polymer nanocomposites

Phase behavior of polymer brushes

Behavior of ions in soft matter systems


Ph.D. in Physics, University of California, Santa Barbara, 1998
