Dr. Wong’s core discipline is chemical engineering, with an emphasis on polymer science and electrochemistry. He has extensive experience working on challenges related to structure-property relationships in polymer/copolymer membranes, morphological characterization of mesoporous materials, and electrochemical characterization of both batteries and fuel cells.

Dr. Wong has experience with a variety of synthetic techniques, including anionic polymerization, hydrogenation of polyolefins, hydrothermal synthesis, and solid state inorganic synthesis. He has experience with several different laboratory techniques for chemical characterization (NMR, GPC/SEC, FTIR), morphological characterization (SAXS, RSoXS, XRD, SEM), electrochemical characterization (AC impedance spectroscopy, cyclic voltammetry, battery cycling, PEM fuel cell testing), and physical characterization (nitrogen physisorption, rheology, tensile strength testing, DSC). He also has experience working as a battery researcher in a Mandarin Chinese-speaking laboratory in Taiwan.

Prior to joining Exponent, Dr. Wong worked as a postdoctoral researcher at the Industrial Technology Research Institute (ITRI) in Hsinchu, Taiwan (R.O.C.) where he first helped establish a laboratory-scale coin-cell battery testing facility and then worked on the development and electrochemical characterization of novel sodium-ion battery electrodes and ionic-liquid electrolytes. Before his postdoctoral research position, Dr. Wong’s Ph.D. research focused on the synthesis and characterization of lined mesoporous membranes using block copolymer/hompolymer blends, which were used as lithium-ion battery separators. The synthesis of these materials resulted in a patent. In addition to synthesis of these materials, Dr. Wong used X-ray scattering (both SAXS and RSoXS) to develop methods for characterizing the morphology of these three-phase mesoporous systems. During Dr. Wong’s undergraduate research and cooperative education work assignment, he worked with PEM fuel cells, studying both the coating optimization of the gas diffusion layer and the electrochemical oxidation of the carbon black.
