Dr. Rizzardi specializes in materials science and metallurgy with particular expertise in the deformation and failure mechanisms of metals, such as high-entropy alloys and Al-Cu alloys, among others. Prior to joining Exponent, Dr. Rizzardi completed his Ph.D. in Materials Science & Engineering at the University of Illinois Urbana-Champaign. His thesis established core concepts regarding the relationships between microstructure, temperature, mechanical loading, and dislocation activity, all of which serve to deepen our understanding of the fundamental deformation processes in metals and their impact on material strength and service life. Beyond experimental techniques, his research specialized in signal processing and advanced statistical analysis and data science techniques.
Dr. Rizzardi previously was a Materials Science team leader for Brunswick Corporation, where he and his team implemented computational tools to predict the microstructure upon solidification of a steel alloy. Their work influenced the casting processes for the next generation of boat propellers. Dr. Rizzardi also previously worked in Johnson Matthey's Noble Metals division. In this role, he provided technical expertise to clients implementing new technological processes, such as platinum coating of ceramics used in glass manufacturing.
Dr. Rizzardi has expertise over a wide range of characterization techniques, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), focused ion beam milling (FIB), as well as ex-situ and in-situ micro- and nanoindentation techniques.
As a native French speaker, Dr. Rizzardi is also involved with various volunteering efforts to assist French-speaking students and newcomers in their integration into American society.
