Dr. Leo Christodoulou is the Deputy Director of the Defense Sciences Office (DSO) of the Defense Advanced Research Projects Agency (DARPA). In addition to his duties as Deputy Director, Dr. Christodoulou serves/has served as program manager of several DSO Materials programs.
Dr. Christodoulou has an extensive record in materials processing and its influence on the microstructure and properties of materials. His expertise encompasses the synthesis, processing, and performance of metallic, intermetallic, and composite materials. His specific interests focus on understanding microstructural evolution through processing and prediction of properties (in particular fracture, e.g., creep, fatigue, brittle fracture, hydrogen embrittlement, and stress corrosion cracking). He is also the co-inventor and primary developer of a class of materials known as XD Alloys.
Dr. Christodoulou obtained his bachelor's degree and doctorate in metallurgy from Imperial College of Science, Technology, and Medicine, London, England. His research in environment sensitive fracture of engineering materials continued at Carnegie Mellon University as a Postdoctoral Research Fellow. Dr Christodoulou joined Martin Marietta Laboratories in 1981 as a scientist, eventually reaching the post of Project Director, Composites. He subsequently rejoined the Department of Materials at Imperial College of Science, Technology and Medicine as a member of the academic staff in 1995 and was conferred the title of Reader, Materials Processing and Performance, in 1997. In 1998 he was appointed visiting professor at Virginia Polytechnic Institute and State University, and in 1999 he joined DARPA Defense Sciences Office as a program manager in the Structural Materials R&D area.
Dr. Christodoulou has authored or co-authored more than 60 technical papers and is a named co-inventor on more than 20 U.S. Patents and their foreign equivalents. For his work in the field of metallurgy and materials science, he has received a number of awards, including the Grunfeld Metal and Prize, Institute of Materials, 1996; Jefferson Cup, Martin Marietta Corporation, 1987; Inventor of the Year, Martin Marietta Corporation, 1987; and several Outstanding Achievement and Excellence Awards.
