Summary of NIST career: My research career at NIST can be divided into six categories of activity: dielectric properties of polymer materials and polymer solutions, characterization of biomedical materials and piezoelectric properties of bone and teeth, piezoelectric properties of polyvinylidene fluoride and construction of piezoelectric transducer devices, the development of instruments for process monitoring, conducting process monitoring experiments using dielectrics, optics, fluorescence and ultrasonics techniques, and the design and construction of a combinatorial melt microrheometer. In each case, I have made significant contributions to the knowledge base in polymer physics. Over the course of my career, I have prepared many proposals for support from other agencies and received favorable response to these proposals from The National Institute for Dental Research (piezoelectric properties of bone), Food and Drug Administration (negative toxicology

control for biomaterials), Eglin Air Force Base, Nuclear Defense Agency, Naval Surface Warfare Center, Naval Ocean Systems (piezoelectric polymer gages), U. S. Army (microwave dielectric properties of polymers) The Electric Power Research Institute (porous tape materials for power transmission) and the Naval Surface Warfare Center (fluorescence monitoring of twin screw extrusion). I have written over ninety archival publications, twenty non-archival publications, and received seven instrument patents. I have presented many invited and contributed talks at national and international scientific meetings and before industry and university audiences. I have organized symposia at national and international meetings and chaired technical sessions at these meetings. I organized several industry/NIST workshops on the technical barriers and measurement problems which processors encounter during manufacturing of polymer products. An outgrowth of these workshops was the formation of The New Measuring Technology for Polymer Processing Consortium, a NIST based R&D collaboration with industry to develop new techniques for polymer processing based on optical methods of measurement. I served as consortium director and chairman of semi-annual consortium meetings from 1992 to 1997. During this period, I petitioned the Society of Plastics Engineers to establish a new special interest group for Process Monitoring and Control and became its first chairman. During the last twenty years of my career at NIST, I focused my attention on polymer process monitoring. I established and directed the NIST process monitoring program and led a team of researchers in the development of new instrumentation while engaging in direct collaborations with industry partners. This work focused on five areas of measurement: dielectrics, ultrasonics, temperature sensitive fluorescent dyes, fluorescence anisotropy, and optical transmission. In each case, we developed new instrument sensors and concepts, and applied these to important manufacturing problems. My research can be characterized by innovative instrument development coupled with applications to manufacturing problems and the construction of mathematical models that yield new technological insights. I have published over sixty proceedings and journal papers and presented dozens of lectures on the topic of process monitoring.
