Expert has two decades of experience as a researcher on structure-processing-morphology-property-performance relationships in polymers (plastics, elastomers/rubbers, thermosets) and composites. He is considered by many researchers to be the world's foremost authority on quantitative structure-property relationships (QSPR) in polymers. He is the developer of a software program implementing the methods developed in his book. Software is used worldwide and has become a plastics "industry standard" software tool for the rapid prediction of polymer properties from their chemical structures. He performs ongoing work to develop new and more powerful polymer property prediction and database search software tools.

He has expertise in composites where the matrix material is a polymer (which can be amorphous or semicrystalline). His expertise encompasses both conventional composites and "nanocomposites". (Nanocomposites are composites designed for use in applications requiring extreme or unique performance characteristics; by “tailoring” the composition, morphology and properties at the nanometer length scale.) His expertise in composites includes the modeling and prediction of physical and mechanical properties, the selection of composite component materials and optimum formulations for obtaining the desired properties, troubleshooting (helping to answer questions such as "why does this composite not perform as expected?"), and the conception of approaches to improve properties and performance characteristics.

He has special strength and an international reputation in the understanding and prediction of structure-processing-morphology-property-performance relationships in polymers (thermoplastics, thermosets, and rubbers/elastomers); and in their blends, foams, films, coatings, and composites; and of the practical product and process implications of these complex relationships. This expertise is based on a deep understanding of the fundamental physics of materials so that it is not limited to specific classes of polymers but instead capable of addressing problems over the full range of industrial polymers. Expert worked for 18 years in a major industrial R&D lab focused on polymer research. A significant fraction of his time was spent in new polymer or composite product design and development projects. His current consulting practice includes, as one of its main focus areas, helping clients with their new product research and development needs and challenges.

The depth and breadth of his expertise in polymer properties, as described in the above paragraph, has been put to practical use during nearly two decades of industrial R&D that involved many polymer design, polymer selection, and composite design problems. Polymers he has worked with have included thermoplastics (both commodity plastics and engineering plastics), rubbers/elastomers, and thermosets. This area is a major part of his ongoing consulting practice.

We live in an era of explosive progress in polymer and composite materials science and technology, as evidenced by the accelerating growth of the scientific literature, patent literature, and trade journal literature. Our technology assessment services help clients derive commercial value from this progress. It is most common for a client to request these services at an early stage of entry into a new technology area so that the recommendations resulting from the assessment can provide both high-level strategic guidance and detailed tactical guidance into the client’s exploration of a technology frontier.

A technology assessment project involves the identification of what is really important in vast amounts of information, the development of sound strategic and tactical recommendations, and the presentation of the findings both in writing and orally in a thorough, effective, and timely manner. The relevant scientific literature, patent literature, and trade journal literature are all studied carefully during most technology assessments. Depending on client needs and wishes, however, a technology assessment can instead be limited to just two or even one of these three general types of sources of information.

Expert has been performing technology assessments for more than a quarter century. His skills in making such assessments were first recognized while he worked at Dow Chemical so that he was given several technology assessment assignments. Such projects now comprise a major component of his consulting practice.

Examples of past technology assessment topics include compatibilization of polymeric systems (polymers, blends, composites, and laminates), impact modification of polymeric systems, carbon nanotubes, nanoclays, nanocomposites, dendrimers, biopolymers (such as polyhydroxyalkanoates), oleochemicals, various textile technology areas, various polymer recycling technologies, plastics-to-fuel conversion technologies, and smart materials.

The main deliverable of each technology assessment project is a detailed formal technology landscape report. This report begins with an Executive Summary providing a concise description, ideal for presentation to the management, of the work that was done and the conclusions that were reached. It continues with a main body consisting of sections providing expanded discussions of the highlights summarized in the Executive Summary. For readers (such as the R&D scientists and engineers of the client) who may need to understand the relevant literature in much greater detail, each technology landscape report ends with an Appendix presenting highlights from each of the cited patents and articles. If requested by the client, an oral presentation can also be prepared.

It is often found during a technology assessment that some of the most promising courses of action include collaboration with external R&D resources such as universities, research institutes, and national laboratories. Our technical project management services are available to help clients build effective "win-win" collaborations in such instances.

Polymers and composites are ubiquitous as materials of construction of products used in a vast range of applications. There are three main areas of focus for enhancing environmental sustainability through polymer and composite materials science. These areas are all major frontiers of research and development worldwide.
• Increasing the percentage of ingredients obtained or derived from environmentally friendly feedstocks used in manufacturing such products.
• Reducing the environmental impact of manufacturing processes.
• Improving the methods utilized for the disposal of used products and of scraps from product manufacturing processes.

The percentage of ingredients obtained or derived from environmentally friendly feed stocks can be increased by the substitution of (a) biobased feed stocks for petrochemical feed stocks and/or (b) recycled feed stocks for virgin feed stocks. It is, however, often difficult to maintain acceptable performance or an acceptable balance of performance versus price in making such a substitution, limiting the maximum possible percentage of substitution.

Manufacturing processes use energy, often utilize various chemicals as processing aids, and may create byproducts that cause pollution. Reducing environmental impact often requires, therefore, (a) the improvement of manufacturing processes to use less energy, (b) the utilization of fewer and preferably no environmentally damaging processing aids, and/or (c) the reduction and preferably elimination of the creation of byproducts that cause pollution.

One approach for reducing the environmental impact of the disposal of used products and of scraps from product manufacturing processes is to convert them via mechanical and/or chemical recycling processes into recycled feedstocks suitable for use as replacement for virgin feedstocks. In some instances where such a conversion cannot be accomplished cost-effectively, conversion into fuels (oils and gases) may provide an environmentally friendlier alternative to placement in a landfill for the disposal of plastic and rubber wastes. The other approach is to manufacture products with biodegradable polymers so that used products as well as scraps from manufacturing processes can be disposed of by composting.
