David W. Riley, PhD

David W. Riley, PhD is a Plastics Rheological Expert specializing in extrusion analysis and polymer defect technology. With a career encompassing analytical instrumentation adaptation and surface chemistry, he brings a nuanced understanding of polymer behavior to litigation work. His work centers on investigating extrusion equipment design, assessing thermal stability of polymers, evaluating whether friction analysis impacts production outcomes.

Mr. Riley has been retained in numerous expert witness and consulting engagements across the plastics and telecommunications industries, involving cases related to telecommunication cables and insulation, and power cables testing. His PhD in Physical Organic Chemistry reinforces his ability to deliver objective, defensible analyses. He is regularly engaged by both plaintiff and defense counsel to provide clear, independent determinations of causation in disputes involving melt rheology and PVC compounding.
