Trevor G Aguirre

Bio

Dr. Aguirre joined Oak Ridge National Laboratory in October 2020 as an Alvin M. Weinberg Distinguished Staff Fellow in the Extreme Environments Materials Process Group at the in the Manufacturing Demonstration Facility. His research centers around processing and properties of additively manufactured ceramics, ceramic-metallic composites (cermets) and ceramic matrix composites. His research goals are to help develop the next generation of ultra-high temperature, harsh environment ceramics, composites and hybrid materials with enhanced thermal, mechanical, and oxidation performance.

He received his Ph.D. in Mechanical Engineering from Colorado State University in 2021, where his dissertation focused on development of bioinspired structures for lightweighting and impact attenuation applications. He has published literature in processing, ceramics, additive manufacturing, and bioinspired design. He also has interest in development of ceramic and/or metallic cellular structures. He has two patent disclosures filed since working at Oak Ridge National Laboratory. He is a member of the American Ceramic Society, ASM International, and the Society of Hispanic Professional Engineers.
