Research Interests

A major scientific objective for the 21st century is to develop a sustainable and environmentally friendly energy economy. To contribute to this goal, we develop efficient and robust materials to catalyze energy conversion reactions. Systems of interest include reduction of carbon dioxide to multi-carbon chemicals and fuels such as n-propanol, and water splitting. We apply state-of-the-art analytical tools such as operando spectroscopy to understand the mechanistic and structural aspects of these processes. This knowledge will then be exploited to design and synthesize systems with improved functionality.
