Dr. Mao is skilled in various characterization techniques that are used to understand the surface and bulk properties of polymer materials used for consumer electronics, including Fourier transform infrared spectroscopy (FTIR), X-Ray diffraction (XRD), inductively coupled plasma — optical emission spectrometry (ICP-OES), scanning electron microscopy (SEM) and transmission electron microscopy (TEM).

Before joining Exponent, Dr. Mao was a graduate researcher at the University of Pennsylvania, and her research focused on precious metal catalysts for automotive catalytic converters. Dr. Mao specializes in the synthesis and characterization of thin-film materials. She has extensive experience in preparing sub-nanometer films using atomic layer deposition (ALD) on porous/flat surfaces for applications of automotive catalytic converters, industrial reactions, and semiconductor industries.
