　　报告人简介：

　　Dr. Snead is a Research Professor at Stony Brook University and the Massachusetts Institute of Technology.  Prior to this, he was a Corporate Fellow and Associate Division Director, Materials Science and Technology Division, Oak Ridge National Laboratory (1992-2015).  He received his PhD from Rensselaer Polytechnic Institute in 1992 where he put forward the use of silicon carbide composites as a low-activation material for fusion reactors, laying the ground work for his early career emphasis at ORNL and an international effort in the area which continues today.  Additional areas of research interest are the development and irradiation effects in ceramics, graphite, and nuclear fuels.  Dr. Snead is a fellow of both the American Nuclear and American Ceramic Societies and was named Distinguished Battelle Engineer and Corporate Fellow of ORNL in 2012.  He was recipient of the American Nuclear Society Seaborg Medal in 2015 for outstanding scientific contributions to the development of peaceful uses of nuclear energy as well as the Mishima Award in 2012 outstanding contributions of an individual in research and development work on nuclear fuel and materials.  He is also the recipient of the American Ceramic Society Richard M Fulrath in 2007 award for research and development of ceramic sciences and materials, particularly involving collaborative research between scientists in the United States and Japan. He served as US DOE Fusion Energy Sciences Advisory Committee Member and currently serves as associate editor for the Journal of Nuclear Materials.  His research activities are equally divided between fusion and fission systems and include both development of new materials and determination of their performance under irradiation environments.  He has published over 300 archival publications and has been cited over 22,300 times.
