Research Interests
My research uses spectroscopy to explore the fundamental optoelectronic properties of solution-processable semiconductors. I am currently especially interested in organic semiconductors and metal organic frameworks. The ultimate goal of this research is to understand how energy flow is controlled at the nanoscale in these materials, and to use this knowledge to help design better materials for low-cost solar energy conversion.
