Dr. Christianson specializes in failure analysis, characterization, and mechanical behavior of materials with an emphasis on metallic materials.

Dr. Christianson's expertise is in the characterization of the process-structure-property relationship within magnesium-based alloys through prototyping and model development. This includes techniques such as alloy fabrication, mechanical testing, optical microscopy, scanning electron microscopy (SEM), electron probe microanalysis (EPMA), Auger electron spectroscopy (AES), x-ray diffraction (XRD), and differential scanning calorimetry (DSC). 

Prior to Exponent, Dr. Christianson worked with QuesTek Innovations as a materials design engineer where he worked on the development of property models and utilization of thermodynamic and kinetic models within the ThermoCalc software to understand the process-structure-property relationship for variable alloys systems. These models were implemented for the design of additively manufactured nickel-based superalloys. His work also involved the design of extreme environment metal matrix composites for friction stir welding.

Dr. Christianson obtained his Ph.D. in Materials Science & Engineering from the University of Florida. His work centered around the development of novel Mg-Li based alloys for use in automotive and aerospace applications. Dr. Christianson's thesis involved the fabrication, mechanical testing, kinetic model development, and characterization of these Mg-Li alloys. The characterization work of these materials involved optical microscopy, SEM, EPMA, XRD, and mechanical testing to understand the effects of alloying elements and thermomechanical processing on the structure property relationship of these systems.
