Educated and trained in polymer science and engineering, Dr. Gai is a material scientist providing consulting service especially for plastic and chemical industries. Her specialization ranges from the polymer synthetic chemistry, block polymer physical phase behavior, to the morphology control and optical application of polymeric composite. Dr. Gai leverages her experience and knowledge in polymeric composite to solve clients’ material issues involving structure-property relationships of materials, living polymerization control, polymer molecular characteristics characterization, crystallization of polymers, morphology investigation, inorganic nanoparticles synthesis, surface modification, polymeric film coating and post processing, rheological study of viscoelastic materials.

Dr. Gai’s experience and background has covered a broad range of advanced characterization techniques. The molecular characterization includes nuclear magnetic resonance (NMR) spectroscopy, Fourier transform infrared spectroscopy (FT-IR), ultraviolet-visible spectroscopy (UV-vis), and gel permeation chromatography (GPC) in both relative and absolute molecular weight measurement. She is proficient in determining glass transition and crystallization of polymeric material using thermal analysis: thermos gravimetric analysis (TGA) and differential scanning calorimetry (DSC). Her strong experience in scattering techniques such as small/wide angle X-ray scattering (SAXS/WAXS) provides detailed structure information of bulk polymeric materials. Dr. Gai is also familiar with microscopy techniques including transmission/scanning electron microscopy (TEM/SEM), optical microscopy (OM) and atomic force microscopy (AFM) for bulk and surface investigation of polymer products.

Prior to joining Exponent, Dr. Gai was a research assistant in Department of Polymer Science and Engineering at University of Massachusetts, Amherst. During her Ph.D. program, she specially studies the nanoparticles distribution in well-ordered block copolymer matrix as a function of particles size, loading, type, and geometry. She also spent time in investigating the bottlebrush copolymers with rapid kinetic ordering over large domain size. She and her collaborators specifically prove that the reduced degree of chain enchantments with the rheological investigation of brush polymers. These copolymers are ideal templates for next-generation hybrid material preparation for their ability in integrating extremely large and high loading functional additives at nanoscale.
