Dr. White assists clients by solving technical problems related to the specification, reliability and sustainability of polymeric materials used in a variety of industries including construction, infrastructure, transportation, chemicals and utilities. One of Dr. White's core competencies is characterizing weather-related changes to the chemical and physical properties of polymers and how those degradative changes may affect end-use performance. This expertise enables him to provide solutions to complex issues related to assessing durability, failure, sustainability, and climate change effects on materials and assets exposed to weathering. He is skilled in developing and utilizing test methods and standards to analyze plastics, rubbers, textiles, metals, glass, and ceramic composite materials. Dr. White is skilled in offering technical guidance throughout all phases of product development including formulation, scale-up, end-use testing and field performance assessments.

Dr. White has extensive knowledge of various polymer characterization (i.e., physical, mechanical, and chemical), analytical and rheological methods (e.g., linear viscoelastic, non-linear, plastic, viscoplastic, rubber modulus, and adhesion). He has researched the areas of fundamental polymer physics; plastic packaging and barrier materials; paints and coatings; plastic pipes; spray foam insulation; adhesives; nanoparticle release; and sealants; additive manufacturing/3D printing; composite materials; rubber gaskets and seals; fibers and textiles; polymer chemical resistance; wire and cable insulation; environmental effects on durability; and product aging. This expertise enables Dr. White to solve problems in a wide variety of areas: building components including building envelope, material selection, and flame retardants; life prediction and fitness for service, paints, and coatings; and risk mitigation and hazard analysis of consumer products, defense, transportation, buildings and structures, paints and coatings, pipelines, and electrical utilities.

Before joining Exponent, Dr. White was a research chemist at the National Institute of Standards and Technology. His research focused on developing new test methods that assess the durability of polymers exposed to weathering. He also worked on projects related to the adhesion of spray-applied fireproofing, blast resistance of trash containers, and material selection for building envelopes. Additionally, Dr. White's has also led multidisciplinary teams focused on sustainability, climate change impacts, enterprise risk management, and community resilience. He was also a credentialed member of the National Construction Safety Team. Dr. White is a fellow of ASTM International, Chair of ASTM C24, Building Seals and Sealants, and an elected officer of the Society of Rheology.

Project Experience

Created and led a multinational consortium that developed a foundational framework to establish new measurement methods to quantify the material durability over two decades. This consortium successfully brought modern polymer science to the building joint sealant industry, as demonstrated by the passage of 17 new and significant revisions of ASTM and ISO standards.

Dr. White has led multi-agency public-private projects to standardize the blast resistance of waste receptacles in public assembly locations (transit systems, stadiums, etc.). The project successfully led to the creation of a baseline security requirement for these locations.

As part of the multidisciplinary task force, Dr. White contributed to the development and adoption of the enterprise risk management (ERM) framework for a principal federal agency.

Led a multidisciplinary, multinational public-private consortium which developed test methods related to the performance of Spray Applied Fire Resistant coatings. This project resulted in improvements to applicable building codes and ASTM test standards.
