MSE Areas: Catalysts, electrochemistry, surface chemistry, fuel cells, batteries, spectroscopy, reaction kinetics
Our research group focuses on efficient, renewable, and environmentally benign catalytic processes for the production of energy, as well as commodity and fine chemicals. We have particular interest in electrochemical systems (fuel cells, batteries, electrolyzers, electrochemical sensors). Emphasis is placed on fundamental characterizations of interactions between molecules and (electro)catalytic surfaces to understand reaction mechanisms for the design and optimization of next-generation catalysts. Broadly, our approach is to employ molecular-level insights from detailed kinetic analysis, quantum chemical calculations, and spectroscopic observations of reactive species and catalyst structures to discern the chemistry and physics relevant to catalyst performance. These insights enable informed, targeted catalyst synthesis strategies to attain ideal structures and compositions that facilitate desirable transformations.
