Computational Theory: Calculation of the electronic and magnetic properties of materials, including composite structural materials, electroceramics, and bioceramics. Development of hybrid methodologies, combining best features of first-principles quantum theory with semi-classical modeling and thermo-dynamics.
A recent example: Reconstruction and relaxation of interface between CFO (cobalt ferrite) and STO (strontium titanate) heterojunctions. (D. Wells, J. Cheng, B.W. Wessels, D. E. Ellis, 2009)
