MY STORY
My research path spans mechanical engineering, computational fluid–structure interaction, and materials science. I completed my Ph.D. in Materials Science and Engineering at Iowa State University, where I focused on rare-earth-containing aluminum alloys and their performance in demanding thermal environments.
Today, my work centers on designing processing routes that control microstructure and unlock useful combinations of strength, ductility, toughness, and thermal stability.
