CMI Researcher Thomas Lograsso began serving as CMI interim director in November 2019. He had led the CMI Focus Area 2, Developing Substitutes since 2014. Previously he led Focus Area 4, Crosscutting Research while serving as the interim director of The Ames Laboratory. Also at Ames Lab, Tom leads a BES Synthesis & Processing effort on Novel Materials Preparation and Processing Methodology, whose goal is to develop synthesis protocols for new materials including quasicrystals, ferromagnetic shape memory alloys, and those that may contain volatile reactive or toxic components especially in single crystalline form. Often his pioneering synthesis efforts result in the first single crystals of these novel materials to be grown and studied for intrinsic behavior.
Tom is co-inventor of a rare-earth free substitute for the magnetostrictive alloy Terfenol-D (contains the critical elements Tb and Dy) used in high precision machining operations for small engine components and as a ultrasonic driver in petroleum exploration. This iron-based substitute is currently being evaluated for commercialization in energy harvesting applications.
Dr. Lograsso received his education in metallurgical engineering at Michigan Technological University, earning his Ph.D. in 1986. He did postdoctoral training working on the Rensselaer team, developing the Isothermal Dendritic Growth Experiment (IDGE) that flew on the Space Shuttle in the late 1990s. The IDGE tested the fundamental solidification physics of the pattern formation and kinetics of crystal growth in isothermal undercooled melts in growth regimes where gravity driven convection overwhelmed the growth in terrestrial conditions.
Matthew Kramer has been Division Director for Materials Sciences and Engineering (DMSE) since 2014. He is also an adjunct professor of Materials Science and Engineering at Iowa State University. As DMSE director, Kramer oversees budgets, proposal preparation, Materials Preparation Center administration, and Sensitive Instrument Facility oversight. DMSE includes 13 FWPs (BES funded), EFRC CATS, approximately 13 additional DOE funded projects, and a small number of Strategic Partnership Projects. Kramer joined Ames Laboratory in 1988, specializing in the areas Structure and properties of glass forming metallic alloys, aperiodic intermetallic alloys, permanent magnets and high temperature alloys, development of in situ time resolved methods using electron microscopy and high energy X-ray diffraction, analytical electron microscopy, and advanced imaging techniques for understanding rapid solidification. He holds B.S. and M.S degrees in geo mechanics and geology from the University of Rochester and a Ph.D. in geology from Iowa State University.
