I specialize in the practice of failure analysis. My background is in mechanical engineering, materials science, and metallurgy. I focus on determining the root cause of failures in a wide variety of products, including machinery, vehicles, pressure vessels, medical devices, consumer products, building materials, and communications equipment. I conduct construction defect investigations of mechanical systems including plumbing and heating, ventilating, and air conditioning installations. My specific areas of interest are fatigue, fracture and corrosion of various materials, including metals, plastics, and fiber composites.
