Ozer Igra has devoted most of his research activities to studying various aspects of shock and blast waves phenomena. His studies include both experimental and numerical investigations of strong (ionizing shocks in argon) and moderate to weak shock/blast wave in gases and in suspensions. Results of his investigations can be found in his many publications available in leading professional journals dealing with gas-dynamic flows and shock waves. He received his B.Sc. and M.Sc. degrees from the Department of Aeronautical Engineering of the Technion, Israel Institute of Technology and his Ph.D. from the Institute for Aerospace Studies, University of Toronto, Canada. He Joined the Ben Gurion University of the Negev in 1971. There he established the Shock Waves Laboratory, supervised many masters, doctorate and post-doc students and served as the chairman of the Department of Mechanical Engineering and thereafter as the Dean of the Faculty of Engineering. He is on the InternationalAdvisory Committee of the International Symposium on Shock Waves (ISSW) and the International Symposium on Shock Interactions (ISIS), and on the editorial board of the Shock Waves Journal.

Kazuyoshi Takayama was born on April 3rd, 1940 in Sapporo Hokkaido, Japan. On March, 1963, he graduated from Nagoya Institute of Technology, entered Graduate School of Tohoku University, Department of Mechanical Engineering obtained Master Degree on March 1965 and obtained Doctor of Engineering on March 1970. He was appointed to be Lecturer of the Institute of High Speed Mechanics of Tohoku University on April 1970 and was promoted to Assistant Professor of the same. He spent his sabbatical from August 1977 to August 1979 in the University of Toronto Institute of Aerospace Studies (UTIAS).
In 1980 he applied double exposure holographic interferometry to quantitatively visualize underwater shock waves which were generated by explosion of lead azide pellets of 4mg in weight. In
