Eng. Expert has been conducting medical device accident investigations for 25 years and product failure analysis for more than 30 years. These failures sometimes involve the actual failure of a metal, plastic, or glass part or a failure of the user. He has had graduate and continuing educational training in failure analysis, stress analysis, fractography, material properties, and electron microscopy. He has brought these skills to play in more than 250 investigations, which resulted in 12 depositions and 3 trial testimonies. The vast majority of his investigations settled out of court because of his properly identifiying the cause of the accident or problem. He is also an expert in oxygen safety and surgical fire safety, having written extensively on both topics.

Several of Eng. Expert's investigations involved surgical staplers, which are used instead of sutures to speed and reduce the complexity of certain surgeries. By examination of the staplers, recovered staples, and excised tissue, he was able to demonstrate that the stapler that these were cases of device misuse and not the fault of the device.By examination of the location of the air intake for a medical air system, Eng. Expert showed that intermittant contaminants were entrained with the intake air and led to poisoning deaths of neonates.A surgical fire case involved an emergency procedure in which an alcohol-based skin prep was inappropriately used. Eng. Expert demonstrated how the fire was started and spread causing the pattern of burns to the patient.Several of Eng. Expert's cases involved catheters. In one case, simple observation of the failure surface of the catheter showed that it was cut with scissors. It was possible that this was a user error or a purposeful act.A purported case of frostbite was attributed to a cooling pad that used ice water. Eng. demonstrated that the device could not cause frostbite and that the injuries sustained were most likely caused by long exposure to wet and cold contrary to the device's and doctor's instuctions for use.
