I have 25 years of experience, and specialize in the field of polymer and fiber science with specific knowledge in the areas of process, structure, property relationships in polymers, polymer characterization by advanced methods, and nanofibers and nanocomposites. I have published on such topics as structure formation during processing of polymer films and fibers, stress induced crystallization phenomnena in polymers and nanofibers via electrospinning. I have testified on high modulus low shrinkage polyester fibers for tire cord. I am an internationally recognized expert in polymer and fiber science. I also have demonstrated experience and expertise in the research, development and commercialization of nanoscale and nanostructured materials, especially polymer nanofibers via electrospinning and polymer nanocomposites comprising metal and metal oxide nanopowders.
