My research involves the theory and modeling of magnetic materials, primarily for information storage. I try to predict macroscopic properties, such as hysteresis loops and magnetic recording noise, from atomic and microscopic information. My two primary tools are micromagnetic simulation and electronic structure theory based on the local density approximation. Other techiques include diffraction theory and molecular dynamics. My choice of research problem is strongly motivated by my industrial experience in the areas of magnetic and optical recording. Typically, my projects involve extensive collaboration with experimentalists.
