Dr. Sadot is an expert experimentalist. He specializes in high-speed phenomena such as shock waves, blast waves and their interaction with structures. Among his subjects of interest are absorbing energy materials, mitigation of shock wave induced loads by passive means, and the dynamic behavior of structures under blast wave loadings. In his laboratory he has several shock tubes capable of Mach numbers from 1.02 to 5 with different cross sections.
