Research Interests

My research focuses on theoretical modeling of novel materials in condensed matter and biological physics settings. Methods of statistical mechanics, quantum mechanics and computer simulation are used to investigate structure, stability and properties of these materials.

Metals in noncrystalline (nonperiodic) structures are a major focus of effort, including: Liquid metals, for example the liquid-liquid transition in supercooled silicon); Metallic glasses, which are multi-component alloys that freeze into a solid while maintaining a liquid-like structure; Quasicrystals, which are partially ordered and highly symmetric structures that are spatially quasiperiodic. These problems are addressed using first-principles total energy calculation coupled with statistical mechanics to model entire ensembles of probable structures.
