#### Current Research Interests

Theory and atomistic modeling of materials, particularly materials interfaces, atomic diffusion, and mechanical behavior of metals and intermetallic compounds. Specific areas of interest include:

- Models of atomic interaction in materials. Development of semi-empirical many-body potentials from experimental data and first-principles calculations.
- Interfaces in materials, including grain and interphase boundaries. Interfacial motion, segregation, chemical reactions and cohesion.
- Atomistic theory and modeling of interfacial kinetics in materials. Relationships between interfacial structure, chemistry, and diffusion.
- Defects and diffusion in intermetallic compounds: diffusion mechanisms, calculation of diffusion coefficients, relation to creep and other high-temperature properties.
- Plastic deformation and fracture of metals and intermetallic compounds. Grain boundary sliding and cleavage.
