Principal
Polymer Science & Materials Chemistry
  • Seattle

Dr. Moalli is a nationally recognized expert in polymeric materials, and addresses issues related to plastics, composite materials, rubbers, adhesives, and general materials science. His specialties include product design and development, analysis of fracture surfaces, combustion behavior, experimental mechanical, chemical and physical property evaluation, development of constitutive relations, fracture behavior, patent analysis, and risk analysis in polymer and polymer composite systems. Dr. Moalli is familiar with risk assessment through use of Failure Modes and Effects Analysis (FMEA) and large-scale accident databases.

Dr. Moalli has published a book and several book chapters on failure of polymeric materials. He has an academic appointment at Stanford University where he teaches a course in Engineering Design, and serves as an academic advisor to undergraduate students. His current areas of research pertain to the evaluation of polymers in medical devices (hip implants, knee implants, breast implants, sutures, catheters, ICD’s), automotive and vehicular applications (fuel tanks, hoses, suspension components, restraint systems, structural composites, helmets), aerospace structures and devices (aircraft composites, fuel system components), construction materials (plastic pipe and fittings, composite pipe, hose, flooring materials, adhesives, windows), electrical (insulation, circuit boards, encapsulants) and recreational equipment (skis, bindings, bicycles, footwear).
