Dr. Kasse is a materials scientist who focuses on failure analysis of commercial lithium-ion batteries and specializes in the microstructural and electrochemical characterization of both lithium metal and lithium-ion technologies. His expertise is in investigating the roles of various battery design strategies - including electrolyte additives, applied mechanical pressure, and electrochemical cycling profiles - on the morphological formation and degradation of lithium metal and graphite anode materials.

He has experience using a wide array of structural and electrochemical analysis techniques, including laboratory and synchrotron-based X-ray diffraction (XRD), X-ray absorption spectroscopy (XAS), X-ray spectromicroscopy, X-ray photoelectron spectroscopy (XPS), small angle X-ray scattering (SAXS), scanning electron microscopy (SEM), cyclic and linear sweep voltammetry, and galvanostatic battery cycling.

Prior to joining Exponent, Dr. Kasse completed his PhD in Materials Science and Engineering at Stanford University, where his research conducted at SLAC National Accelerator Laboratory focused on using synchrotron-based X-ray surface characterization and electrochemical analysis to understand fundamental interfacial processes in lithium metal and lithium-ion batteries. Before graduate school, he worked as an engineer for the United States Air Force, developing test and evaluation hardware and software for conducting over land and over water weapons testing. He completed his BS and MS in Materials Science and Engineering at the University of Florida, where he studied rare earth-doped ceria electrolyte materials for intermediate temperature solid oxide fuel cells (SOFCs).
