Biography

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). She previously chaired the Gordon Research Conference on Polymer Physics (2018) and served as Chair of the APS Division of Polymer Physics (2020-2021). Her research is currently focused on molecular simulation of ion-containing polymers and electrolytes, in particular to better understand ion transport in polymer membranes for energy applications.
