I have 26 years of experience, and specialize in the field of explosive damage assessment with specific knowledge in the areas of vapor cloud explosions aboard offshore oil platforms, blast injuries to personnel and fragmentation effects. I have published on such topics as damage to the buildings, computer-based prediction of personnel injury due to an explosion and primary fragmentation parameters. I have testified on explosion at the plants, damage to structures resulting from explosion at mine site and damage to office building resulting from collapse of the world trade center south tower. I developed the first detailed injury model of the human body due to blast and fragmentation.
