Since 1993, my research has focused on simulating material properties and developing advanced numerical methods. My projects have included both continuum and atomistic simulations. Applications for continuum methods include the modeling of a crystal growth instability in a stressed solid, and crack propagation in ceramics. Applications for atomistic methods include the use of molecular dynamics to study two-dimensional melting, and first principles methods to study extended defects in semiconductors. Advances in numerical methods include the development of a new extremely accurate crack tip element and the derivation of exact Green's functions for exponetially graded materials.

Example Projects

• Modeling a Growth Instability in a Stressed Solid
• Discovery of a New Effect of Stress in Solids: A Kinetically Driven Interfacial Instability
• Advanced Numerical Methods are used to Model the Growth Instability
• A New Highly Accurate Crack Tip Element
• Boundary Integral Analysis for Functionally Graded Materials
• Two-Dimensional Melting
• Edge Dislocations in Silicon
