Science and Engineering of Casting Solidification

Professor Doru Michael Stefanescu graduated with a Dipl. Eng. degree in Metallurgical Engineering from the University Politehnica Bucharest, Romania in 1965 and obtained a Ph.D. in Physical Metallurgy from the same institution in 1973. In 1980 he served as a Visiting Professor at the University of Wisconsin, Madison and then joined the University of Alabama where he taught and did research until 2005 when he retired. He continued his scholarly activity as Ashland Designated Research Professor at the Ohio State University till 2010. Professor Stefanescu has conducted 39 Master of Science theses and 17 Philosophy Doctor dissertations. He has authored and co-authored 397 publications. He is a Doctor Honoris Causa of the Technical University of Cluj-Napoca, Romania (1998), the University Transilvania, Brasov, Romania (2001) and Jonkoping University, Sweden (2012). He is a Honorary Professor, University Politehnica, Bucharest, Romania (2006) Prof. Stefanescu's research interests include experimental and numerical aspects of solidification processing, influence of low-gravity on solidification, processing of metal-matrix composites, processing of ceramic superconductors, manufacturing technologies and physical metallurgy of cast iron, steel and nonferrous alloys, and cast metals technology. He is recognized as a world expert in cast iron. Dr. Stefanescu honors and awards include Fellow of the ASM International (1997), the Award for Scientific Merit of the American Foundry Society (2000), the Joseph Seaman Gold Medal of the American Foundry Society (2011), Honorary Member of the Romanian Academy of Technical Sciences (2012), the John Campbell Medal from the Institute of Cast Metals Engineers, United Kingdom (2012). Dr. Stefanescu is currently Cudworth Professor of Engineering Emeritus, The University of Alabama, and Professor Emeritus, The Ohio State University.
