Dr. Lee’s professional research interests include the design, synthesis, and characterization of polymeric materials. Her academic and industrial research background incorporated her skills in polymer synthesis, mechanical and optical characterization, and structure-property relationships to create “smart” elastomers, evaluate the flow properties of toners, and synthesize new anti-reflective coatings for the microelectronics industry.
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. 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 mechanical environments and have potential applications as materials with built in force or damage detection capabilities.
Dr. Lee has extensive experience with a variety of polymer synthesis techniques including polyurethane synthesis and radical polymerization. Her previous research has required the use of a broad range of molecular characterization techniques including nuclear magnetic resonance spectroscopy (NMR), 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), tension testing, and fluorescence imaging.
