Research Summary

Our research is focused on developing computational models to understand materials for emerging energy technologies in the fields of solar energy, batteries, and fuel generation. The critical steps in these technologies involve electron transfer at complex interfaces. We will focus on using theoretical and computational approaches to reveal design principles that connect molecular structure to the important material properties required for these applications, with the goal of developing an understanding that can be used to guide experimental studies.

Photochemistry and Excited-State Dynamics

Storing solar energy as chemical fuels is critical to reduce our dependence on fossil fuels and meet increasing energy demands. We are particularly interested in photocatalysis involving plasmonic metal nanostructures because of their strong and highly tunable absorption spectra, focusing on understanding how the structural features that influence the mechanism, yield, and lifetime of the charge-transfer state can be tuned to enhance photocatalysis.

Reactions at electrochemical interfaces are critical for energy technologies such as fuel generation and next-generation batteries. In many cases, the efficiency of these technologies is limited by large overpotentials and limited selectivity for the desired products. We are developing computational approaches that allow us to explore reaction mechanisms at electrochemical interfaces, gaining understanding of the features of the electrode surface and solution composition that can be tuned to optimize the efficiency of these reactions for improved device performance.
