1. Develop accurate micromagnetics to analyze domains and loops of magnetic materials
2. Simulation of magnetic devices such as heads, MFM tips in magnetic recording industry
3. Design of hard disk drives by simulation of read/write process of 0-1 data in disk media.

My research interest is the theory of applied magnetism: micromagnetics. The magnetic materials and devices used in magnetic recording industry is the main focus. I brought up proper periodic boundary conditions for FDM-FFT Micromagnetics using Landau-Lifshitz equations. With polycrystalline microstructure included, we can explain the soft and hard magnetic properties of thin films and devices in magnetic recording and spintronics applications. Recently we developed Hybrid Monte Carlo Micromagnetics, as a new method to explain the M-H loops and domains at finite temperature.
