Research
My research focuses on fundamental rock magnetism, specifically using advanced simulation techniques and numerical modeling to understand how magnetic particles in rocks and meteorites record and preserve information about ancient magnetic fields over geological timescales. I develop and apply parallelized micromagnetic finite element models to investigate magnetic domain structures in magnetic minerals across different size ranges—from single-domain to pseudo-single-domain to multi-domain states. A key focus of my work is understanding the thermal stability and recording fidelity of magnetic remanence, including how factors such as cooling rate, particle size, shape, and magnetic domain configurations (for example single-vortex states) affect the reliability of paleomagnetic records. This research has important implications not only for interpreting paleomagnetic data from terrestrial rocks and extraterrestrial materials, but also for applications in materials science, data storage technologies, and other fields where understanding magnetic behavior at the nanoscale is critical.
