Research Interests

d- and f-block organometallic chemistry; small molecule activation chemistry; homogeneous catalysis

Research Overview

We make and study reactive and unusual complexes of the rare earths, actinides, and early transition metals. We use these to make new catalysts for difficult transformations such as hydrocarbon C-H bond activation and carbon dioxide chemistry. Our labs have state-of-the-art equipment for the synthesis of highly air-sensitive complexes, and the study of their reactivity towards small, inert molecules, particularly for the development of new homogeneous catalysts.
