Associate Professor, Mechanical Engineering

Garritt TuckerProfessor Tucker joined the Mechanical Engineering department at Mines in the summer of 2017 as an Assistant Professor, and is now an Associate Professor who is active in the interdisciplinary Materials Science program at Mines. Before joining the faculty at Mines, he spent four years as an Assistant Professor in the Department of Materials Science and Engineering at Drexel University (Philadelphia, PA), and two years as a Postdoctoral Research Appointee at Sandia National Laboratories (Albuquerque, NM) in the Computational Materials and Data Science group. While at Drexel, he was awarded the Outstanding Teacher Award in 2015 and the TMS Young Leader Professional Development Award in 2016. Professor Tucker earned his PhD in 2011 from the Georgia Institute of Technology (School of Materials Science and Engineering), and a BS in 2004 from Westminster College (Salt Lake City, UT) majoring in both Physics and Mathematics. During his time at Westminster and Georgia Tech, he received several distinctions including the Outstanding Physics Senior Award, Academic All-American (Soccer), and a Sigma Xi nomination.

His research group at Mines integrates high-performance computing and theory to discover the fundamental structure-property relationships of materials that will enable the predictive design of advanced materials with tunable properties. Of particular interest are materials where defects and interfacial-driven properties can be effectively tuned or controlled to enable property enhancement, such as nanocrystalline alloys, multicomponent laminates, materials for energy storage, 2D materials, and hierarchical metals. At the core of his group’s approach is to develop collaborations and programs that effectively mesh computation with experiment to tailor functional materials.

Recent work by Prof. Tucker and his group has provided unprecedented understanding into a new defect in layered materials that influences not only the strength of the material, but also other advantageous properties such as strain reversibility and kinking nonlinear elastic response. His work has also addressed many outstanding questions regarding grain boundary properties and structure in metals, and extended this idea to modeling realistic material microstructures. A significant focus has been on providing a fundamental understanding of the mechanics and physics of nanocrystalline alloys – quantifying the roles of grain boundaries, dislocations, and twinning. Their work has recently highlighted how microstructural features can be altered to systemically tailor the operative nanoscale deformation mechanisms within metallic materials. Prof. Tucker’s research group leverages a number of computational methods to research materials and their properties, such as density functional theory, atomistic modeling (e.g., molecular dynamics and statics), phase-field models, and a number of multiscale modeling approaches. Beyond those traditional computational methods, Prof. Tucker and his research group also employ innovative postprocessing tools for data analysis and visualization, and pursue novel informatics techniques to build predictive methodologies for materials design.
