Our group studies light-matter interactions in materials for optoelectronic devices, including molecular and polymer systems for organic electronics as well as biohybrid and biomimetic systems for novel emerging technologies. Our goal is to understand how intermolecular coupling interactions in these disordered systems drive device function. Ultimately, we want to elucidate the balance between order and disorder in these materials, and to develop a framework to use this balance to our advantage in developing new optoelectronic devices.
We develop and study new systems based on molecular semiconductors and photoactive proteins. Light-driven processes in these materials occur across a broad range of timescales. We use time-resolved absorption and photoluminescence spectroscopies to explore electronic photoexcited processes in a variety of materials. Our setups allows us to characterize photophysical mechanisms from the femtosecond to millisecond timescale, and from the visible to the near infrared spectral region.
