Our group supports the development of performance-based standards for technologies used by law enforcement, corrections, emergency response, and the military; and advances these technologies to support the needs of these stakeholders by leading standards development organizations to develop standards and conformity assessment programs and establishing reference measurement facilities. We perform basic phenomenology and measurement science research to support the advancement and application of ballistic-resistant and trauma-mitigating materials, concealed object sensing and imaging, high-strength polymeric materials, and advanced composites.
