The main activities of Claude Estourn�s are devoted to the synthesis, preparation and densification of materials (with nano and micro scales, composite, multilayered system, ceramic, polymer, glass etc..) by "Spark Plasma sintering" technology and to the development of novel, specific and multi-functional architectures to tailor specific properties. Javier Garay Professor, Mechanical Engineering, U.C. San Diego, USA. Javier Garay, Ph.D. is the principal investigator of a vibrant experimental laboratory called the Advanced Material Processing and Synthesis (AMPS) Lab. Research in the AMPS Lab focuses on advanced material processing and synthesis with particular emphasis on designing the micro/nanostructure of bulk materials for property optimization. Professor Garay received his B.S. in Mechanical Engineering (1999), M.S. in Materials Science and Engineering (2002) and Ph.D. in Materials Science and Engineering (2004) all from the University of California, Davis. He joined the Jacobs School of Engineering at UC San Diego in 2015. Prior to that he was a professor of Materials Science & Engineering and Mechanical Engineering at UC Riverside where he also served as Chair of the Materials Science & Engineering Program from 2012-2015. Professor Garay has received two federal Young Investigator Program (YIP) awards: Army Research Office (ARO-YIP) in 2005 and Air Force Office for Scientific Research (AFOSR-YIP) in 2009. He also received the Faculty Early Career Development (CAREER) award from the National Science Foundation in 2010. Roberto Orru Professor, Dept. of Mechanical, Chemical and Material Engineering, University of Cagliari, Italy. Roberto Orr� received his Master Degree in Chemical Engineering at the University of Cagliari in 1991 and his PhD degree in Metallurgical Engineering at the Polytechnic of Torino in 1997. He became Assistant Professor in 1998, Associate Professor in 2002 and Full Professor in 2014. He has been visiting scholar and visiting scientist for about 2 years at the Department of Chemical Engineering and Materials Science, University of California, Davis, USA, during in 1996-1999.
