My research is primarily focused on studying oxide quantum materials, especially in the thin film heterostructure form. These quantum materials exhibit a plethora of properties such as Magnetism, Superconductivity, Ferroelectricity, and Rashba spin orbit coupling. These attributes make oxide quantum materials as potential candidates for developing oxide based electronics and quantum technologies.
