Maxwell Wallace

Postdoctoral Research Associate

(509) 335-7054

Scientific Interests and Work:

Dr. Wallace’s current work is focused on understanding structural (elastic limit, inelastic structural deformation, phase transformation, etc.) and thermodynamic response of shock compressed crystals along different crystallographic directions.

Shock wave loading by means of the plate impact method provides an unmatched approach to investigate materials under extreme dynamic conditions. Transformations across a planar shock front can be accurately determined from the shock wave parameters obtained via the plate impact method. Thus, fundamental insight of detailed material behavior in nanosecond timescale can be obtained.

Background:

Dr. Wallace received his B.S. and M.S. in Chemistry from Central Washington University (advisor: Dr. Anthony Diaz). His research at CWU was on understanding electron-hole pair trapping efficiency of rare earth doped phosphor compounds under vacuum ultraviolet excitation. Dr. Wallace received his Ph.D. in 2019 from Oregon State University (advisor: Dr. Mas Subramanian). His Ph.D. dissertation research was on fundamental structure – property investigations of novel metal oxides (honeycomb layered, perovskite, spinel, pyrochlore, etc.) and intermetallics with a focus towards topological insulators, quantum spin liquids, superconductors, and thermoelectric materials.
