Trained as a material scientist with a specialization in polymer science, Dr. Lee’s research and experience spans the chemistry, physical properties, and mechanical behavior of polymeric materials. Her areas of expertise include structure-property relationships of materials, mechanics of materials, adhesion science, chemical and physical compatibility of materials, and fractography. Dr. Lee leverages her knowledge of polymer science in a wide variety of proactive and reactive projects including investigations in automotive, consumer electronics, construction, medical, and piping industries. She has assisted clients with materials selection and specifications, formulation, end-use testing, product safety evaluations, and failure analysis, including failure of polymers by environmental stress cracking, fatigue, stress overload, creep overload, and weathering.
Dr. Lee has extensive experience with the characterization of materials. Her previous research and work experience has required the use of a broad range of molecular characterization techniques including, Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, ultraviolet-visible spectroscopy (UV-Vis), and gel permeation chromatography (GPC). In addition, Dr. Lee has evaluated the bulk physical properties of polymeric materials by utilizing differential scanning calorimetry (DSC), thermo gravimetric analysis (TGA), atomic force microscopy (AFM), bulk mechanical testing, and fluorescence imaging. Dr. Lee is also familiar with polymer conversion processes such as injection molding, compression molding, blow molding, extrusion, and thermoforming.
Prior to joining Exponent, Dr. Lee was a research assistant in the Department of Material Science and Engineering at the University of Illinois at Urbana-Champaign, and had work assignments at Xerox and Dow Corning. During her time at Xerox and Down Corning she studied the flow properties of toners and investigated new novel block copolymer synthesis techniques, respectively. At the University of Illinois, she was a member of the collaborative Autonomous Materials Systems at the Beckman Institute working in the area of mechanochemistry. Her research involved the incorporation of force-sensitive chemical groups (mechanophores) directly into the backbone of polymers (e.g., polyurethanes) to impart new functionalities to materials, such as self-sensing (i.e. color change) and self-healing. These “smart” polymers autonomically respond to changing environmental conditions and are capable of intrinsically detecting applied forces or subsequent mechanical damage.
