Dr. Lin is a materials scientist specialized in multifunctional polymers and composites. His expertise includes designing, synthesis and characterization of piezoelectric materials, self-healing polymers and nano-structured composite interfaces. He has extensive experience in chemical characterization using infrared spectroscopy (IR), Raman spectroscopy, X-ray diffractometry (XRD) and nuclear magnetic resonance (NMR), as well as thermal analysis techniques such as thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). He also has expertise in surface characterization and ferroelectric measurement using atomic force microscopy (AFM). He is well-versed in fabrication and failure analysis of plastics and fiber/nanofiller reinforced thermosetting composites. Dr. Lin has also developed additive manufacturing methods for thermoplastic/thermoset polymers and composites.

Prior joining Exponent, Dr. Lin was a research assistant in the Macromolecular Science and Engineering department at the University of Michigan. He conducted research on chemical modification of piezoelectric polymers to improve the piezoelectrical performance of commercialized materials and developed novel 3D printing methods to fabricate wearable piezoelectric sensors and energy harvesters. He conducted research on Diels-Alder based self-healing polymers and developed formulations with high self-healing capability as well as excellent mechanical properties and thermal resistivity. He also investigated nanoscale composite reinforcements to simultaneously improve the stiffness and toughness of thermoset matrices.
