Toward Intelligent Materials Design and Manufacturing: From Atoms to Airplanes
Abstract: As the world moves toward autonomous experimentation, microscopy provides a foundational tool on which to develop and build the necessary data science foundation for these toolsets. Tracking dynamic processes generates large data sets that are often only analyzed after the experiment is over. In this talk, a path forward toward real-time data processing, in operando, is discussed. Examples of operando control of 2-dimensional materials as well as bulk metals are presented, revealing the ability to tailor operando experiments with precision. The results provide a look into the future of “bespoke” materials and the leading role of next generation electron microscopy in these efforts. Our work exploring local structure evolution toward damage-tolerant high entropy alloys via both high throughput and precision techniques will be reviewed. Finally, an outlook on emerging time resolved studies and key challenges for “big data” will be discussed as a foundation for future integration of ML during synthesis and processing experiments, ranging from 3D printing to in situ microscopy.
Bio: Mitra Taheri is a Professor of Materials Science & Engineering at Johns Hopkins University (JHU) and a Chief Scientist at Pacific Northwest National Laboratory. At JHU, Taheri also serves as the Director of the Materials Characterization and Processing Center (MCP), and leads the “Dynamic Characterization Group,” focusing on the development and use of in situ microscopy and spectroscopy to characterize microstructural evolution and properties of materials and structures in a wide variety of environments (from aerospace to biomedical) and external stimuli. More recently, Taheri’s work has focused on developing artificial intelligence and machine learning tools to tackle both high throughput and precision materials synthesis and characterization. Taheri received her BS, MS, and PhD in Materials Science and Engineering from Carnegie Mellon University, followed by an NRC Postdoctoral Fellowship at the Naval Research Laboratory and a Director’s Postdoctoral Fellowship at Lawrence Livermore Laboratory. She spent 11 years at Drexel University as the Hoeganaes Endowed Chair Professor in Metallurgy before joining the faculty at JHU. She is a native of Washington, D.C., and currently resides in Baltimore, MD, with her husband and two sons.
