Michael Ortiz

Michael Ortiz is the Frank and Ora Lee Marble Professor of Aeronautics and Mechanical Engineering at the California Institute of Technology (Caltech), affiliated with the Division of Engineering and Applied Science. His research focuses on solid mechanics, multiscale material modeling, and computational mechanics. He leads a group studying material behavior across length and time scales, including fracture mechanics, data-driven methods, and hydrogen embrittlement. His work bridges fundamental science and engineering applications, emphasizing real-world problem-solving through applied mathematics and computational tools.

Research interests include the physics of solid materials under diverse conditions, multiscale modeling of metals and composites, and the development of advanced numerical methods. Notable projects involve ultrasonic neuromodulation, hydrogen storage in magnesium alloys, and topology optimization of lithium-ion battery anodes. He collaborates internationally on initiatives like the Data-Driven Computational Mechanics project and the M-HEAT hydrogen embrittlement study.

Ortiz has advised over 40 PhD and master’s students, contributing to impactful research in fracture mechanics, materials science, and computational methods. His funded projects span NIH-supported neuromodulation studies to EU-funded hydrogen economy initiatives. He is actively involved in the Solid Mechanics group at Caltech and collaborates with institutions globally, advancing interdisciplinary research in mechanics and materials.
