In the Waldie Group, we are developing novel transition-metal complexes and supramolecular structures with targeted reactivity for catalysis (e.g. electro-reduction of water and carbon dioxide, electro-oxidation of liquid fuels) and materials applications (e.g. opto-electronic devices, heterogeneous catalysis). We apply concepts from synthetic inorganic and organometallic chemistry coupled with electrochemistry and spectroscopic techniques to prepare, understand, and optimize our systems and their reactivity.
