My specialties lie in the unique challenges and physiology of injurious environments, especially underwater, certain aspects of outer space, and from exposure to physically traumatic events such as explosions. I began my career working as a civilian mechanical engineer for the US Navy, where I specialized in the design, function testing, and safety testing of underwater equipment and breathing systems intended for use by military personnel, and I was both the project engineer and project manager for the first approval effort for a new military underwater breathing system to be successful since the 1970s. Concurrent with part of my employment with the navy, I earned a doctorate degree in biomedical engineering from Duke University, specializing in injury biomechanics, which is the application of the principles of engineering to determine the injury mechanisms and safe limits during events when human beings are at risk of injury or death. My goal for my career is safety and prevention...
