    Expert Witness Response E-064616

    I have experience in failure analysis of materials and finding the root cause of failure due to flaws in design and/or materials defects. As a university professor, I teach and research in areas of materials mechanical properties, product design and development, and materials engineering. I have worked as an expert witness in several failure analysis cases. For this particular case, I would need to inspect evidence and examine any fractured part by a scanning electron microscope.
