Justin SchwartzJack E. Crow Professor of Engineering, Florida State University & Adjunct Professor, MS&E and NRE, Georgia TechBiographyJustin Schwartz has been involved in research and teaching in applied superconductivity for over 20 years. His Ph.D. research at MIT included the design of the superconducting magnets for the ARIES I commercial fusion reactor study. After completing his PhD in 1990, he was a Visiting Scientist at the National Research Institute for Metals in Tsukuba, Japan, where he worked with Dr. Hiroshi Maeda shortly after his discovery of superconductivity in the Bi-Sr-Ca-Cu-O system. From 1990-1993, he was an Assistant Professor of Nuclear Engineering at the University of Illinois. In 1993, he moved to the Florida State University as an Associate Professor of Mechanical Engineering and as the Leader of the High Temperature Superconductor Magnets and Materials Group at the newly formed National High Magnetic Field Laboratory. He has remained at FSU since and is currently the Jack E. Crow Professor of Engineering. He teaches a variety of courses, including those in mechanics, superconductivity and materials for energy systems, and advises graduate students in mechanical engineering, electrical engineering and physics. He is the author of over 140 peer-reviewed journal publications and in 2003 his research group set the world record for magnetic field generation by a superconducting material (25.05 T), a record that continues to stand. He has received a number of awards, and was elected as a Fellow of the IEEE. He is the currently the Editor-in-Chief of the IEEE Transactions on Applied Superconductivity.

Current ResearchHis current research interests include the engineering issues of applied superconductivity, including quench detection and protection, electromechanical behavior, fatigue, magneto-optical imaging, the effects of irradiation on superconducting behavior, and an integrated approach to materials processing and magnet manufacturing. He has recently begun new initiatives in the use of magnetic fields in materials processing and low temperature electrical and mechanical behavior of carbon nanotube based composite materials. He collaborates with a number of industrial partners, including American Superconductor Corporation, Supercon, Inc., and Nove Technologies. Other research interests include the effects of irradiation on advanced materials, including nanomaterials and boron carbide. |
