My research entails the synthesis of new ligands and transition metal complexes with the ultimate goal of uncovering new approaches to the catalytic activation and functionalization of small molecules and organic substrates. These types of processes are critical for the development of sustainable energy technology and for the catalysis of organic transformations.
Although I am interested in a number of different projects, the underlying theme for my research program is to examine the ways in which different components of a transition metal complex work together and how this cooperation affects the reactivity of the complex as a whole. Specifically, I am interested in examining the cooperation between
- two metal centers in bimetallic frameworks
- metal centers and non-innocent ligands
Although the primary focus of my research is synthesis, the research pursued by my group also entails a large variety of characterization techniques including multinuclear NMR, IR, UV-Vis and EPR spectroscopies, as well as magnetic and electrochemical measurements. In addition, theoretical investigations into the electronic structure and reactivity of particularly interesting transition metal complexes synthesized in my research group are studied using density functional theory (DFT) calculations.
