Mary Louie is a research scientist in the Hardware Systems Laboratory. Mary’s areas of expertise include electrochemistry, solid-state ion transport, energy conversion and storage, and gas pipeline property characterization and safety. She is passionate about clean energy and improving the way energy is produced, managed, and utilized. She is currently developing an electrochemical system that produces ammonia at moderate temperatures and pressures. Prior to joining PARC, Mary was a consultant at Exponent where she specialized in materials characterization and failure analysis of consumer products and engineering structures, spanning electronics and batteries to medical devices and pipelines. She has performed root cause analyses of failed batteries as well as ruptured gas pipelines, and has performed assessments of nondestructive tools for characterizing gas pipeline properties. Mary has over eight years of research experience studying ion transport and electrocatalysis in fuel cells and electrolyzers. Her work centered on the rational design of electrocatalysts through an understanding of reaction mechanisms. As such, she has extensive experience developing tools for interrogating electrochemical reactions under operating conditions - including electrochemical atomic force microscopy, confocal Raman microscopy, and X-ray spectroscopy. As a postdoc, she investigated the structure-activity relationship in alkaline water splitting electrocatalysts. As a graduate student, she studied electrolyte and electrode materials for solid acid fuel cells. Dr. Louie holds a Ph.D. and an M.S. in Chemical Engineering from Caltech, and a B.S. in Chemical Engineering and Materials Science and Engineering from UC Berkeley. She has authored publications garnering over 2,000 citations and has been honored with a UC President’s Postdoctoral Fellowship, Ludo Frevel Crystallography Scholarship, and National Science Foundation Fellowship.
