Research Description
My research in experimental condensed matter physics aims to discover, synthesize, and characterize novel quantum materials, such as superconductors, frustrated magnets, and multiferroic materials. After synthesizing these materials in-house, I use advanced techniques like X-ray diffraction, neutron scattering, magnetic and transport measurements, and microscopy to explore and tune the electronic phase diagrams of strongly correlated materials by applying control parameters such as chemical doping, pressure, and magnetic fields.
