Sierra Astle


Sierra Astle is a Materials Science PhD student at Colorado School of Mines. She is advised by Dr. Corinne Packard in the Colorado Center for Advanced Ceramics. Sierra received her Bachelors of Science in Materials Science and Engineering from Penn State University in 2023, graduating with honors. During her time at Penn State, Sierra conducted research on the structural properties of calcium aluminosilicate glass systems, doing molecular dynamics simulations with the goal of creating a statistical mechanics model to describe the entropy and enthalpy of formation of oxygen triclusters within the system. She also did work batching and characterizing novel low-carbon silicophosphate glass systems for their mechanical properties such as hardness and crack resistance. She is interested in exploring how to make renewable energy cheaper and more efficient. In her free time, Sierra enjoys hiking, bouldering, and learning to play guitar.
