Our research is inspired by chemical, material, and engineering challenges that underlie critical problems in sustainability. We are particularly interested in developing new ways to synthesize chemicals and fuels that use CO₂ as a feedstock instead of petrochemical resources. Scalable processes that “recycle” CO₂ have the potential to substantially mitigate emissions and constitute an important step toward carbon-negative technologies. The approaches we take are tailored to the application and encompass both thermochemical and electrochemical transformations. Our work spans diverse activities including studies of structure-activity relationships in heterogeneous catalysis, solvent-free chemistry, gas–solid reactions, and the design, engineering, and modeling of electrochemical cells.
