Our group tackles emerging challenges in water, energy, and sustainability using nanomaterials. Through the design of ultrathin nanostructures and coatings, we create membranes that can separate contaminants from water, catalysts that drive difficult chemical reactions, and materials enable the formation of previously unobtainable device architectures. We combine atomically-precise synthesis, advanced characterization approaches, and data science tools to better understand the behavior of molecules in these uniquely small systems and use that understanding to invent scalable processes that can enable the deployment of clean-energy technologies.
