Multiscale Characterization of High Performance Alloys under Additive Manufacturing Conditions, Dr. Amy J Clarke

​

Amy J. Clarke is a professor in the George S. Ansell Department of Metallurgical and Materials Engineering, Co-Director for the Center for Advanced Non-Ferrous Structural Alloys, and a faculty member with the Advanced Steel Processing and Products Research Center at the Colorado School of Mines (Mines). She also holds a joint appointment with Pacific Northwest National Laboratory and is a Guest Scientist at Los Alamos National Laboratory (LANL).

​

Her research focuses on physical metallurgy and making, measuring, and modeling metallic alloys during processing to realize advanced manufacturing. She also performs multiscale materials characterization with electrons, x-rays, neutrons, and protons, such as real-time imaging of metallic alloy solidification dynamics during simulated additive manufacturing and ultrafast diffraction during deformation.

​

Amy earned her B.S. degree from Michigan Technological University (MTU) and her M.S. and Ph.D. degrees from Mines in Metallurgical and Materials Engineering. Prior to joining Mines, she was a Scientist and Seaborg Institute Postdoctoral Fellow at LANL and Senior Engineer – Development/Research at Caterpillar Inc. Amy has received a U.S. DOE Office of Science Early Career Research Program Award, an Office of Naval Research Young Investigator Program Award, and a Presidential Early Career Award for Scientists and Engineers (nominated by the U.S. Department of Energy and the National Nuclear Security Administration’s Defense Programs), the highest honor bestowed by the United States government on science and engineering professionals during the early stages of their careers.

​

Amy has served on The Minerals, Metals & Materials Society (TMS) Board of Directors and Association for Iron & Steel Technology Board of Directors, as Chair of the Advanced Photon Source Users Organization at Argonne National Laboratory, serves on the MTU College of Engineering and Materials Science and Engineering External Advisory Boards, is an Editor for Metallurgical and Materials Transactions A, and was named a 2018 Fellow of ASM International and a 2020 TMS Brimacombe Medalist.
