Dr. Loewen is an inorganic chemist by training, specializing in air-free synthetic small molecule synthesis, characterization, and electrochemistry. She is experienced with numerous characterization techniques including FTIR, GC-MS, CT, NMR, UV/Vis, and single molecule X-Ray diffractometry. She has also applied electrochemical techniques such as cyclic voltammetry, differential pulse voltammetry, and controlled potential and controlled current electrolysis to assess catalyst performance for energy storage applications.

At Exponent, she leverages her fundamental electrochemistry knowledge and characterization experience to address problems in multiple industries, including energy storage systems, where she assesses the quality, performance, and failure of batteries for a broad spectrum of applications. She also supports a variety of consumer product industries by using analytical techniques to identify contaminants and evaluate chemical contributions to the failures of polymeric materials.

Prior to joining Exponent, Dr. Loewen developed in situ FTIR spectroelectrochemical methods for detecting highly reactive catalytic intermediates, and studied fundamental catalyst structure-property relationships to gain deep mechanistic understanding of selective electrocatalytic CO2 reduction.
