Research interests

My research is focused on understanding and tailoring solid-state phase transformations in a variety of technologically relevant magneto-functional materials. These materials are essential to modern society by allowing wireless interconversions between different types of energy to functionalize a variety of advanced technologies in automotive, aerospace, energy, and biomedical fields. Research applies novel materials processing approaches to alter local atomic environments and structures at multiple length scales – Ångstrom-level to the microscale, to tailor magnetofunctionality. The main methodology combines thermal, magnetic, and/or mechanical inputs during material treatment, using the home-designed Multi-Driver furnace, for soft or hard ferromagnetic material systems such as FeSiB-based amorphous-nanocrystalline materials, MnAl-, and FeNi-based alloys.
