Education:

PhD in Solid State Physics, Department of Physics and Chemistry, Moscow Institute of Steel and Alloys, Russia, 1985

Honors and Awards:
  • Alexander von Humboldt Research Fellowship, 1993 
  • World's Best Husband Award*, 1996
    *Awarded by my wife Julia 
  • International Award of the High-Temperature Society of Japan, 2002; 2004

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