Eric R. Homer

Eric R. Homer is an Associate Professor of Mechanical Engineering with research and teaching emphases in Materials Science & Engineering. As a Materials Scientist and Mechanical Engineer, Eric investigates how the atomic- and micro-scale structure of materials affects their macroscopic properties that can be used in the design and construction of engineering structures. His main research focus is in computational materials science where he has developed models and software to simulate a variety of material phenomena. Prior to joining the faculty at BYU in 2011, Eric researched grain boundary migration and microstructure evolution as a postdoctoral researcher in the Computational Materials Science & Engineering Department at Sandia National Laboratories (Albuquerque, NM). While completing his Ph.D. in Materials Science and Engineering at the Massachusetts Institute of Technology, Eric examined the process of shear banding in amorphous metals and was awarded the National Defense Science and Engineering Graduate (NDSEG) Fellowship. Eric's love of BYU began with his time pursuing B.S. and M.S. degrees in Mechanical Engineering at Brigham Young University.

Our research group focuses on modeling various material processes such as: grain boundary structure-property relationships (for both atomic and crystallographic structures and properties of grain boundary energy, mobility, diffusivity, and grain boundary-dislocation interactions), microstructure evolution, and mechanical behavior of metallic glasses and metallic glass matrix composites.
