I earned my B.S. in Physics from Ulsan National Institute of Science and Technology in South Korea.
I started my Ph.D. studies in the spring semester of 2020 at the Ulsan National Institute of Science and Technology and plan to complete my degree by the spring semester of 2025.
I am interested in strongly correlated systems and frustrated spin systems, particularly in quantum materials that exhibit unconventional electronic and magnetic properties. I have studied a variety of single-crystal systems where electron-electron interactions and geometric frustration give rise to exotic quantum phases and quasi-particle. Expanding on this, I am also deeply interested in exploring thin film systems, where quantum states can be engineered by tuning parameters such as strain, dimensionality, and interfacial effects.
In particular, I have synthesized and studied perovskite oxide thin films, which provide a versatile platform for investigating correlated electron behavior, emergent magnetism, and metal-insulator transitions. By precisely controlling the growth conditions, I have explored how strain, composition, and heterostructuring influence their electronic and magnetic properties. Moving beyond perovskite systems, I have also synthesized delafossite-based thin films, which offer an intriguing setting to study novel spin textures and frustrated magnetic interactions. These materials exhibit unique transport and magnetic properties due to their layered structure and strong electron correlations, making them promising candidates for exploring unconventional quantum phases.
To investigate these quantum phases, I employ various optical and synchrotron-based spectroscopy techniques, including Fourier-transform infrared spectroscopy (FTIR), ellipsometry, and magneto-optical spectroscopy, to probe the electronic structure, spin dynamics, and phase transitions in thin films. Additionally, I have extensive experience utilizing synchrotron radiation techniques such as (time-resolved) X-ray diffraction (XRD), X-ray absorption spectroscopy (XAS), and X-ray magnetic circular/linear dichroism (XMCD/XMLD) to explore structural, electronic, and magnetic properties under different external stimuli. By integrating these experimental approaches, I continue to explore new ways to understand and manipulate complex quantum phenomena in correlated electron systems.
