Dr. Song is a chemical engineer and polymer scientist by training with an expertise in developing photo-curable materials, stimuli-responsive polymers, and thermosetting composites for biomedical device applications. Her research specialties include photochemical processes, polymer syntheses, resin formulations, and structure-property relationships. Aided with her research background in polymer characterization, Dr. Song actively engages in root cause failure analysis of industrial polymers. In addition, Dr. Song is a registered patent agent, assisting clients with intellectual property matters.

Dr. Song has utilized a wide spectrum of characterization techniques for analyzing physical, mechanical, chemical, and optical properties of polymers. These include but are not limited to Fourier Transform Infrared Spectroscopy, Dynamic Mechanical Thermal Analysis, Thermogravimetric Analysis, Differential Scanning Calorimetry, Rheometry, Tensometry, UV/Vis Spectroscopy, and Nuclear Magnetic Resonance Spectroscopy. Dr. Song has extensive research experience in photopolymerizations, step-growth polymerizations, and free radical chain-growth polymerizations for the development of dental restorative composites.

Prior to working at Exponent, Dr. Song worked as a postdoctoral researcher at ADA Science & Research Institute (ADASRI) and as a contractor at National Institute of Standards and Technology (NIST). Her research focused on developing stimuli-responsive polyelectrolytes and antimicrobial polymers for Class V dental restorative materials. Before working at ADASRI and NIST, Dr. Song received a Ph.D. in Chemical Engineering from University of Colorado at Boulder where she studied developing UV-curable glassy thermosets based on "click" chemistries with high toughness and ductility for 3D printing applications.
