Biographical Sketch

Dr. Marvel is an Assistant Professor in the MIE Department at LSU. His main research interests are focused on Materials Science and Engineering topics, namely: (i) processing-structure-property relationships of atomic-scale defects (e.g., grain boundaries), (ii) metastable processing methods to design novel materials (e.g., high-energy mechanical alloying and atmospheric plasma spray), (iii) application of aberration-corrected scanning transmission electron microscopy (STEM) to evaluate atomic-structure and chemistry, (iv) Monte Carlo grain growth simulations, and (v) employing mixed reality applications to accelerate data acquisition, analysis, and training of novice users on characterization instruments. Dr. Marvel is active in ASM International and currently serves on the Board of Directors for the International Metallographic Society. He was a recipient of the 2023 ASM Bronze Medal Award.
