The Lee group focuses on functional polymeric materials (e.g. electronic conductors, ion conductors, redox-active) for energy and sensor applications. The current focus is on batteries, thermoelectrics, and wearable sensors. The Lee group has a strong expertise in the synthesis and characterization of polymers that allows us to understand charge transport, electrochemical and morphological properties. We frequently leverage synchrotron x-ray scattering and spectroscopy techniques to advance our understanding of functional polymers at the molecular, nano-, and micro-scale.
