Dr. Yan is a material chemist with a focus on nanomaterials and electrochemistry. Her specialty is analyzing the correlation between structures and properties at the molecular level and the materials’ performance on the macroscale level. At Exponent, Dr. Yan applies her experience in synthesis and characterization of battery electrode materials to evaluate the components and performance of batteries as well as identify the root cause of their failure.

Dr. Yan has extensive experience in materials characterization techniques including optical microscopy, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), UV-visible (UV-Vis) and Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), spectroscopic ellipsometry, nitrogen porosimetry and BET surface area analysis, dynamic light scattering (DLS), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). She is also well-versed in standard electrochemistry testing techniques including potentiostatic and galvanostatic methods as well as impedance spectroscopy. Additionally, she has synthesized a range of nanomaterials, with particular expertise in mesoporous nanostructures with tunable optical, electronic and electrochemical properties for improved device performance.

Prior to joining Exponent, Dr. Yan was a graduate research assistant at University of California Los Angeles. Her research focused on developing nanostructured functional materials for advanced lithium-ion battery electrodes and thermally insulating window coating. She developed several structures and methods to improve high rate performance of Li-ion battery electrode materials. Dr. Yan also worked as a Tech Fellow at UCLA Technology Development Group, assisting with technology landscape analysis and marketing effort for UCLA inventions.
