About
A common theme in our research is using light‒matter interactions and electrical energy to measure, drive and control interfacial chemical transformations at the nanoscale. In particular, we are interested in advancing our fundamental understanding of the interconversion of chemical and electrical energy. We are pursuing two approaches to accomplish this goal: (1) Develop and employ high resolution optical microscopy and spectroscopy to reduce ensemble averaging in electrocatalysis to directly measure chemical and catalyst intermediates and (2) control microenvironments at electrocatalysts to enhance activity and selectivity. We aim to gain and leverage mechanistic insight in chemical reactions to achieve high efficiency and selectivity in fuel generation/consumption reactions and increase the performance of high-capacity, rechargeable batteries.
