I have 30 years of experience, and specialize in the field of polymers, plastics with specific knowledge in the areas of failure of plastics, stabilization of plastics and plastics processing. I have published on such topics as plastic piping, trenchless technology and piping markets. I have testified at trial on sewer pipe rehabilitation. The polyethylene piping products that I developed have been sold for over twenty six years. Over 5 billion lbs and $3 B of sales of these products have occurred. These products have been in continuous service for that time and are projected to still be serviceable for many years to come.
