Research Interests:

The principal effort of our research program is on computational design and multi-scale description of new materials, starting from the electronic structure, and building up to the molecular and nano-levels. Specifically, we have two major focuses: novel artificial metallo-enzymes and metallo-cluster-enzymes based on physiological and non-physiological transition metals and main group elements; and bio-mimetic doped catalytic surfaces. This ambitious pursuit requires simulations of systems in their entirety, and we develop the necessary methodology and algorithms. On the macro-scale, modeling entails mixed quantum mechanical (QM) and molecular mechanical (MM) treatments, sometimes in conjunction with statistically averaged, ensemble descriptions. On the atomic scale, the interplay between molecular structure and underlying electronic structure is in question, further calling for advancements in the general theory of chemical bonding, and tools for the unbiased search for the most stable structural forms and transition states. We collaborate with experimental laboratories in molecular biology, surface science, and spectroscopy. Ideologically, this research program is directed toward solving medicinal and energy-related problems facing humankind, and it is facilitated by these outlined methodological and fundamental advancements.
